General Description
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
Absolute Maximum Ratings
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
