CHA4220-98F
0.5-20GHz Driver
GaAs Monolithic Microwave IC
Description
The CHA4220-98F is a distributed driver
amplifier which operates between 0.5 and
20GHz.
It is designed for a wide range of
applications, such as military, telecom, test
instrumentation.
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 supplied as bare die part with RF
accesses matched on 50 ohms.
