CHA2157
RoHS COMPLIANT
55-60GHz Low Noise / Medium Power Amplifier
GaAs Monolithic Microwave IC
Description
The CHA2157 is a two stages low noise and
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.
The circuit is manufactured with a HEMT
process, 0.15µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
