General Description
Mimix Broadband’s two stage 10.0-21.0 GHz GaAs
MMIC buffer amplifier has a small signal gain of 17.0
dB with a +19.0 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.
