General Description
Mimix Broadband’s 4.5-10.5 GHz QFN packaged receiver has
a noise figure of 1.8 dB and 13.0 dB conversion gain across
the band. The device integrates an LNA, image reject mixer
and LO buffer amplifier within a fully molded 4x4mm QFN
package. 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.

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
