CHX2093a RoHS COMPLIANT 10-30GHz Frequency Multiplier GaAs Monolithic Microwave IC Description The CHX2093a is a cascadable by 3 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 to simplify the assembly process. The circuit is manufactured with a pHEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography.
