Mimix Broadband’s 33.0-40.0 GHz GaAs MMIC transmitter has

a small signal conversion gain of 8.0 dB with a 30.0 dB LO/RF

isolation. The device has a pair of sub-harmonic mixers

configured to form an image reject mixer which requires an

LO at 15.5-21.5 GHz. This is followed by a two stage LNA. The

image reject mixer reduces the need for unwanted sideband

filtering before the power amplifier. The use of the

sub-harmonic mixer makes the provision of the LO easier than

for fundamental mixers at these frequencies. I and Q mixer

inputs are provided and an external 90 degree hybrid is

required to select the desired sideband. 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, LMDS, SATCOM and

VSAT applications.

recommended to keep channel temperature as low as

possible for maximum life.
