20-40GHz Medium Power Amplifier
GaAs Monolithic Microwave IC
Description
The CHA3093c is a high gain broadband four-
stage monolithic medium power amplifier. It is
designed for a wide range of applications, from
military to commercial communication
systems. The backside of the chip is both RF
and DC grounded. This helps simplify the
assembly process.
A B.I.T. ( Build In Test ) monitors a DC voltage
that is representative of the microwave output
power.
The circuit is manufactured with a PM-HEMT
process, 0.15m gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
