CHA3080-98F
71-76GHz Medium Power Amplifier
GaAs Monolithic Microwave IC
Description
The CHA3080-98F is a three-stage
monolithic Medium Power Amplifier. This
circuit includes a power detector which
integrates a directional coupler, a detection
diode and a reference diode to be used in
differential mode.
It is dedicated to E-band telecommunication,
particularly well suited for the new generation
of high capacity Backhaul.
The circuit is manufactured with a pHEMT
process, 0.1µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
It is available in chip form with BCB layer
protection.
