Description

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.
