The MADR-011007 is a 40-bit serial to parallel driver in a low cost 6 mm 48-lead PQFN plastic package. It is designed as the serial control interface for MACOM’s transmit module MAIA-010365 and receive module MAIA-009579. A 20-bit multiplexer is designed on-chip to provide TX bits control capability. High speed digital CMOS technology is utilized to achieve low power dissipation. Even though it is designed to drive GaAs FETs using a -5 V power supply, it can also be used as a general serial to parallel converter when using a +5 V power supply.
This driver, used in conjunction with MACOM’s MAIA-010365 S-Band radar transmit module, MAAP-011022 S-Band 7 W high power amplifier, and the MAIA-009579 receiver, provides a complete chipset for S-Band dual polarization air traffic control and weather radar applications.
