The Key Things We Learned at OFC 2017   Apr. 18, 2017

OFC2017.JPGThe value of tradeshows are hotly debated in our digital age. With hundreds of ways to interact, communicate and advertise, tradeshows can be seen as less and less relevant, and increasingly time consuming and costly. Many companies find themselves questioning whether tradeshows are worth the investment.

After participating in numerous technology tradeshows over the decades and across a wide range of markets, MACOM fully recognizes the value of attending these events. In a previous blog, we discussed the numerous benefits of attending and participating in technology tradeshows, including the opportunities to announce breakthrough technology, display compelling demonstrations, interact with diverse attendees, and engage in vigorous exchanges of ideas and harmonization. And when it comes to doing technology tradeshows right, no event stands out more prominently than the Optical Fiber Communication Conference (OFC).

What exactly is OFC doing right?

  1. Enabling Technology Innovation – Every big player in the optical industry gathers for OFC, which means every hot and relevant topic in the industry is represented. Perhaps most outstanding this year were the advances taking place in Data Center and Long Haul/Metro solutions to support escalating need for bandwidth growth. The buzz this year was all about speeds and feeds, and getting the fastest speed with the least number of feeds. Enabling 100G to 400G on a single wavelength was a major accomplishment. Over 140 product, service, partner and technical advancement announcements were made during the event, including MACOM’s own L-PIC for Data Centers and 600G on a single wavelength for Long-Haul/Metro announcements.
     
  2. Offering Unlimited Networking Opportunities– OFC is undeniably a must-attend event for anyone in the optical industry. Drawing around 15,000 attendees and over 660 exhibitors this year, OFC is the premier show in the optical space, showcasing the latest innovation in technology and creating a prime avenue for networking. With every year, the demand for meeting room spaces increases as open marketplace booth space shrinks to accommodate. Exhibitor hours set no constraints on the willingness of attendees to enclose themselves in open air meeting rooms or claim a few chairs in the coffee area to talk. Customers, competitors and students alike are given an opportunity to discover and discuss. OFC offers a tremendous opportunity to engage, share and shape thinking, allowing the industry to actively develop their understanding and further enhance technology innovation.
     
  3. Empowering Information – More than a tradeshow, OFC is a conference that aims to inform and educate its attendees. Presentations, panels, interactive workshops and technical speakers use the week to share expertise and field questions; during the OFC 2017 event, over 1,100 peer-reviewed papers were submitted, and conference hours expanded into the weekend to accommodate the thriving industry. In a recent video interview with OSA, MACOM’s Ray Moroney summarized the resulting value of OFC: “By bringing the entire industry together for a week, it really enables innovation across the whole supply chain.”

As an enthusiastic OFC attendee and component vendor sitting in the middle of this optical ecosystem, MACOM values the opportunities to share and grow at each event. This year we had a host of product announcements, and took full advantage of representing our developments in presentations, forums and panel discussions throughout the week. We welcomed the opportunity to meet with customers and offer private demonstrations to further solidify our position as the preeminent supplier of optical components supporting the industry’s growing demand for data capacity. With another exciting tradeshow behind us and plenty of information gleamed, MACOM is already looking ahead to OFC 2018 and the possibilities that await. For all these reasons, we continue to find tremendous value in technology tradeshows—especially those like OFC.

Are You a Microwave System Design Engineer Concerned with Time-to-Market?   Apr. 04, 2017

By their very nature, Monolithic Microwave Integrated Circuits (MMICs) are designed to make it easier for engineers to architect RF systems. Combining multiple component functions within a single DIE or package, MMICs take a lot of the speculation and complexity out of the design cycle compared to systems built primarily with discrete RF devices.

Despite the design efficiencies that MMICs enable, prototyping an end-to-end RF system can be a tedious process. Every component needs to be individually characterized, and the datasheets, spreadsheets and app notes can pile up quickly. Designing, fabricating, assembling and testing prototype systems requires substantial time and cost, and often requires several iterations. A typical bench prototype is shown below:

Even the most experienced RF system engineers can struggle to achieve first-pass design success, particularly when they’re grappling with aggressive design requirements for higher frequencies, lower power consumption, smaller size and lower costs. And as frustrations mount with each new tweak to the component circuitry – and ‘time to market’ gets longer and longer – there isn’t an engineer among us that hasn’t pondered the possibility that there must be a better way.

Actually, there is.

MACOM is continuing to look for ways to make it easier for designers to get to market faster with their MMIC-based systems. Through our collaboration with X-Microwave, designers can quickly and easily prototype and simulate end-to-end RF systems with ‘building block’ flexibility using MACOM MMICs.

X-Microwave’s ideal system utilizes drop-in and cascadable components called X-MWblocks that can be seamlessly interconnected with each other on a prototype plate, with no soldering required. There are hundreds of X-MWblock components for engineers to choose from, spanning every function in the RF design chain – all of which have been pre-characterized.

The photos below provide a good overview of the X-MWsystem’s key attributes.

First, X-MWblocks such as MACOM’s 22 GHz Amplifier (MAAP-011247) with Integrated Bias Tee can be individually tested as shown in image below (image courtesy of X-Microwave).

We at MACOM always appreciate innovative RF/microwave engineering when we see it, and X-Microwave’s ‘building block’ X-MWsystem is a particularly elegant design. For a video overview of how the platform works, be sure to check out the 3D animation of the X-MWsystem in action. Any engineer – from novice to expert – who’s ever wrestled with RF system design will be encouraged by what they see.

Center Stage at OFC 2017: Breaking New Barriers in Optical Bandwidth Density   Mar. 20, 2017

DatacenterB.pngWith OFC 2017 in full swing this week, vendors from across the optical networking industry are gathered in Los Angeles to showcase the latest and greatest products and technologies targeted for Cloud Data Centers, client access and metro and long haul applications. Across all of these apps, skyrocketing data rates are putting ever increasing pressure on data center and network operators to maximize their bandwidth density, measured in bit rate per available space and power budget. It’s no surprise then that “cost per bit” metrics will be top of mind at OFC this year.

As hundreds of millions of new subscribers and new Internet of Things (IoT) infrastructure come online in the years ahead, it’s imperative that we work together to accelerate the transition to higher-performing, power and space efficient optical interconnects at 100G and beyond. OFC affords vendors and customers alike an ideal forum to compare notes and connect in-person with the community of technologists that are driving major innovations in this domain.

Cloud Data Centers are particularly affected by our collective efforts to drive down per-bit delivery costs. Whereas telecom service providers can today justify the investment in 100G technology for decades-long deployment, data center operators will initiate network upgrades every three to five years, incrementally growing their bandwidth capacity at cost structures that are 1/5 of existing infrastructure. 

MACOM at OFC 2017

MACOM has a host of product announcements and demonstrations on tap for OFC 2017, and our subject matter experts will be well represented in live presentations and panel discussions throughout the week. This year, we are excited to play what we believe is a leading role enabling the upgrade from 10G to 100G optical connectivity within Cloud Data Centers. MACOM brings to bear the proven cost structure, capacity and supply chain flexibility that achieved preeminent market share in the PON Access market, and products and platform innovation that achieved similar success with 100G technology in Long Haul, Metro and DCI networks.

All are invited to join us at booth #1736 to talk trends and learn more about our optical technology portfolio – a portfolio that’s growing quickly through intensive in-house R&D and strategic acquisitions. Speaking of which, we’re delighted to join forces with our new colleagues from Applied Micro at OFC this year, where we’ll highlight the unique value of our combined solution for 100G data center connectivity, spanning PAM-4 DSP, linear driver and linear TIA specifically designed to enable 100G per lambda transceiver modules, with a clear pathway to 400G.

RF Energy in Daily Life Part 3: Medical Applications   Mar. 07, 2017

RFEnergyBlogMedical.jpgEarlier blog posts in our “RF Energy in Daily Life” series have highlighted the many advantages that Gallium Nitride (GaN) technology enables for solid state cooking and plasma lighting applications, where GaN is widely expected to make a transformative impact across commercial and industrial market segments.

We use this word a lot – “transformative” – when talking about breakthrough semiconductor technologies, and rightly so when one considers the far-ranging implications of these technologies for our daily lives. In this blog post we’ll assess the promise of GaN for medical applications, where GaN-based RF devices will improve physicians’ abilities to save lives and enhance the quality of life for patients around the world. When technology and healthcare innovation intersect, it doesn’t get much more transformative than that. 

KEY GaN ADVANTAGES

Today’s RF medical devices are designed to heat biological cells and tissue for medical treatments ranging from RF/microwave ablation to bacteria sterilization, with minimal invasiveness. Compared to legacy semiconductor technologies, GaN offers these key advantages:

Precision control – GaN is capable of offering high efficiency at ISM frequencies below 3 GHz, while also supporting frequencies up to 5.8 GHz and higher. The higher the frequency, the shorter the wavelength, enhancing the precision and control of the RF energy field. This improves treatment accuracy while simultaneously reducing the risk of damaging adjacent tissues and organs.

High power with better efficiency – GaN delivers raw power density that is considerably higher than LDMOS, with 10% better efficiency. This enables more power to be directed to the treatment site to dehydrate and/or burn away tumors and unwanted tissue, with reduced power consumption and thermal constraints at the system level.

TARGET APPLICATIONS, TODAY AND TOMORROW

RF/microwave ablation techniques are commonly employed today for removing cancerous tumors, and will see continued improvement as GaN enters the RF medical device market. The evolution to higher efficiency opens the door to expanded use in cosmetic surgery and dentistry.

Hyperthermia therapy is quickly emerging as another core target application for RF energy. Typically practiced in combination with other cancer treatments, physicians can use targeted RF energy to elevate the temperature of patients’ body tissue at the cancer site. The controlled heat (104 oF to 108oF) stresses the cancer cells and reduces cancer cell replication without impeding DNA replication among healthy cells. This technique holds great potential as a mainstream cancer treatment in the years ahead.

Looking to the future, we envision that GaN-based RF medical devices will be used for warming blood and organs for transfusions and transplants. In the case of blood transfusions, RF energy can enable stored, chilled blood to be heated quickly and uniformly without creating harmful toxins, allowing rapid transfusions in emergency situations. Similarly, the ability to freeze and rapidly defrost donated organs without causing cellular damage could extends the organs’ shelf life and increase the odds of a successful donor/recipient match over longer timeframes and distances.

The widespread adoption of GaN for RF energy applications in commercial, industrial and medical domains heralds exciting changes that will impact all of us, and may even extend our lives. Be sure to keep abreast of MACOM’s continued innovation in the months ahead as we work with our partners and customers to bring these transformative technologies into the mainstream.
