General Description
Absolute Maximum Ratings
Mimix Broadband’s three stage 37.0-40.0 GHz GaAs
MMIC buffer amplifier has a small signal gain of 21.0 dB
and 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.

(1) Channel temperature directly affects a device’s MTTF. Channel temperature
should be kept as low as possible to maximize lifetime.
(2) For saturated performance it recommended that the sum of
(2*Vdd + abs(Vg)) < 9V
