CHA5293A

CHA5293a 17-24GHz High Power Amplifier GaAs Monolithic Microwave IC Description The CHA5293a is a high gain three-stage monolithic high power amplifier. 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. It is available in chip form.
