CHA3512
RoHS COMPLIANT
6-18GHz Low Noise Digital Variable Amplifier
GaAs Monolithic Microwave IC
Description
The CHA3512 is composed by a Single Pole
Double Through (SPDT) switch followed by
a one step digital attenuator and a double
stage travelling wave amplifier. 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, 0.25µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
It is available in chip form.
