detector at the output. Gain control up to
REF
15dB is achievable thanks to gate voltage.
It is a field proven solution for Point to Point RFIN
RFOUT
telecommunication systems, also suitable for
other applications such as SATCOM. The
circuit is highly linear and compatible with the
last generation of Digital Pre-Distortion. Its
versatile biasing condition helps to tune the
performances. The circuit is manufactured with a pHEMT
