Mimix Broadband’s 19.0-26.0 GHz GaAs MMIC receiver has a noise
figure of 2.5 dB and 20.0 dB image rejection across the band. This
device is a two stage balanced LNA followed by an image reject
sub-harmonic anti-parallel diode mixer and includes an integrated LO
buffer amplifer. The image reject mixer eliminates the need for a
bandpass filter after the LNA to remove thermal noise at the image
frequency. The use of a sub-harmonic mixer makes the provision of
the LO easier than for fundamental mixers at these frequencies. I and Q
mixer outputs 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.
