CHA3513
RoHS COMPLIANT
6-18GHz 3 bit Digital Variable Amplifier
GaAs Monolithic Microwave IC
Description
The CHA3513 is composed by a three steps
digital attenuator followed by a three stage
travelling amplifier and a Single Pole Single
Through (SPST) switch. It is designed for
defense applications. The backside of the
chip is both RF and DC grounded. This helps
to simplify the assembly process.
RF
IN
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.
