CHA2494-98F
RoHS COMPLIANT
34-44GHz Low Noise Amplifier
GaAs Monolithic Microwave IC
Description
The CHA2494-98F is a wide band monolithic
low noise amplifier.
It is designed for
a
wide range of
Vg
applications, from military to commercial
communication systems.
The circuit is manufactured with a pHEMT
process, 0.15µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
