CHX2091

CHX2091 20-40GHz Frequency Multiplier GaAs Monolithic Microwave IC Description The CHX2091 is a cascadable by 2 frequency multiplier monolithic circuit. It is designed for a wide range of applications, from military to commercial communication 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.
