The XB1008-QT is a two stage 10 - 21 GHz GaAs
MMIC buffer amplifier that has a small signal gain of
17 dB with a 18 dBm P1dB output compression
point. The device also provides variable gain
regulation with adjustable bias.
The device is ideally suited as an LO or RF buffer
stage with broadband performance at a very low
cost. The device comes in an RoHS compliant 3 mm
QFN surface mount package offering excellent RF
and thermal properties. This device is specifically
designed for use in PtP radio applications and is well
suited for other telecom applications such as
SATCOM and VSAT.
