CHA3514 Datasheet (United Monolithic Semiconductors)

CHA3514, GaAs Monolithic Microwave

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 pHEMT process, 0
