CHR2291 Datasheet | United Monolithic Semiconductors

12-17GHz Integrated Down Converter Ga As Monolithic Microwave IC Description The CHR2291 is a multifunction chip which integrates a LO time two multiplier, a balanced cold FET mixer, and a RF LNA. It is designed for a wide range of applications, typically mercial munication systems. The backside of the chip is both RF and DC grounds. This helps simplify the assembly process. The circuit is manufactured with a PM-HEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form.
