General Description
Mimix Broadbands 36.0-42.0 GHz GaAs transmitter has a +17.0 dBm
output third order intercept across the band.This device is a balanced,
resistive pHEMT mixer followed by a distributed output amplifier and
includes an integrated LO doubler and LO buffer amplifier.The use of
integrated LO doubler and LO buffer amplifier makes the provision of
the LO easier than for fundamental mixers at these frequencies. I and Q
mixer inputs are provided and an external 90 degree hybrid is required
to select the desired sideband.This device uses Mimix Broadbands
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 Millimeter-wave Point-to-Point Radio,
LMDS, SATCOM and VSAT applications.
