General Description
Mimix Broadband’s 4.5-10.5 GHz receiver has a noise figure
of 1.6 dB and 14.0 dB conversion gain across the band. The
device integrates an LNA, image reject mixer and LO buffer
amplifier within a single, compact MMIC. 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 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. This device is well
suited for Point-to-Point Radio, LMDS, SATCOM and VSAT
applications.

(1) Operation of this device above any one of these parameters
may cause permanent damage
(2) Channel temperature directly affects a device’s MTTF. Channel
temperature should be kept as low as possible to maximize lifetime
