General Description
Mimix Broadband’s two stage 4.0-11.0 GHz GaAs MMIC
buffer amplifier has a small signal gain of 23.0 dB with a
+20.0 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 3x3mm QFN
surface mount package offering excellent RF and
thermal properties.This device is well suited for
Microwave and Millimeter-wave Point-to-Point Radio,
LMDS, SATCOM and VSAT applications.
