General Description
Mimix Broadband’s 18.0-25.0 GHz GaAs MMIC transmitter has a
+20.0 dBm output third order intercept and 15.0 dB image
rejection across the band. This device is an image reject sub-
harmonic anti-parallel diode mixer followed by a balanced two
stage output amplifier and includes an integrated LO buffer
amplifier. The image reject mixer reduces the need for

use of a 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
