CHA3514 RoHS COMPLIANT 6-18GHz 4 bit Digital Variable Amplifier GaAs Monolithic Microwave IC Description The CHA3514 is composed by a two stage travelling wave amplifier followed by a four steps digital attenuator. It is designed for defense applications. The backside of the chip is both RF and DC grounded. This helps to 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.
