General Description
Mimix Broadband’s 19.0-26.0 GHz GaAs packaged receiver has a
noise figure of 3.0 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 device 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 device comes in a 7x7 mm QFN Surface Mount
Laminate Package offering excellent RF and thermal properties and
is RoHS compliant. This device is well suited for Millimeter-wave
Point-to-Point Radio, LMDS, SATCOM and VSAT applications.
