... 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 designed for defense applications. The backside of the chip is both RF and DC grounded. This helps to simplify the assembly process. ...
