General Description
Mimix Broadband’s three stage 35.0-45.0 GHz GaAs
MMIC buffer amplifier has a small signal gain of 23.0
dB with a noise figure of 2.7 dB across the band. This
MMIC uses Mimix Broadband’s 0.15 µm GaAs PHEMT
device model technology, and is based upon electron
beam lithography to ensure high repeatability and
uniformity. The chip has surface passivation to protect
and provide a rugged part with backside via holes
and gold metallization to allow either a conductive
epoxy or eutectic solder die attach process. This
device is well suited for Millimeter-wave
Point-to-Point Radio, SATCOM and VSAT applications.

(1) Optional low noise bias Vd1,2,3=3.5V, Id=50mA will typically yield 3-4dB decreased P1dB and OIP3.
(2) Measured using constant current.
(3) Unless otherwise indicated Min/Max over 35.0-45.0 GHz and biased at Vd=4.5V, Id1=28mA, Id2=42mA, Id3=84mA.
(4) Unless otherwise indicated Min/Max over 35.0-45.0 GHz and biased at Vd=3.5V, Id1=9mA, Id2=16mA, Id3=25mA.
