Mimix Broadband’s 18.0-30.0 GHz GaAs MMIC receiver has a 12.0 dB gain
control range, a noise figure of 3.5 dB and 25.0 dB image rejection across
the band. This device is a three stage LNA followed by a single transistor
"Tee" attenuator and an image reject fundamental resistive HEMT mixer.
At high signal levels the radio AGC system can be used to reduce the
receiver gain improving the IIP3 providing for minimum distortion at
modulation schemes as high as 256 QAM (ETSI-see Technical Note 1).
The image reject mixer eliminates the need for a bandpass filter after the
LNA to remove thermal noise at the image frequency. 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.
