How many pit stops does a race car driver make? As few as necessary to win a race.


How many times does a signal need to be retimed in a link? Ideally, once. By the receiving end point which then processes the data. If the far end receiver has the horsepower to compensate for the entire channel, it should be given the opportunity to do so. If the receiver is not capable of meeting link level performance, retiming can be leveraged to improve bit-error performance by segmenting the link into more manageable portions.

Designing with PIN Diodes: Discrete, HMIC or AlGaAs?

discrete small blog.jpg (903548438)At first glance, implementing a solid-state RF or microwave switch does not seem to be a daunting task: identify and evaluate an appropriate integrated circuit (IC) switch and if none exists, select PIN diodes to include in a discrete, custom design. Millimeterwave RF switches seem to be a bit more challenging, due to the high frequency of operation.

Designing with Diodes: Protecting Sensitive Components

receiver protect limiter blog.jpg (!blank)Sensitive low noise amplifiers (LNAs) in radar or radio receivers cannot tolerate large input signals without sustaining damage. What’s the solution? Receiver-protector limiter (RPL) circuits, the “heart” of which typically comprises PIN diodes, can be utilized to protect sensitive components from large input signals without adversely affecting small-signal operation.

RF and microwave diodes come in multiple different offerings, ranging from PIN and varactor to Schottky diodes. Manufacturers often specify these diodes by parameters which can be measured without the need for a diode to be permanently connected to an external circuit.

Non-Linear Transmission Line Comb Generators Part-2: Solutions to the Low Phase Noise Problem

Part 2.png

Overview

In this two part series from MACOM, we will delve into Non-Linear Transmission Line (NLTL) Comb Generators.  Inpart 1we considered the phase noise problem and introduced a potential solution to the problem. In this second part of the blog series, we will explore NLTL comb generation, compare it to its predecessor comb generation using Step Recovery Diodes and see how the NLTL comb generation approach can enable improved sensitivity and lower bit error rates in communication systems.
