General Description
Mimix Broadband’s 5.5-8.4 GHz GaAs HBT wide tuning feedback
MMIC VCO is designed to operate using an on-chip filter to provide
the necessary oscillation conditions. The oscillator consists of a
linear Lange coupled phase-shifter, a Lange coupled quadrature
generator, a differential amplifier, a four-quandrant I/Q modulator
and an output buffer differential amplifier. The device also contains
a divide-by-four frequency divider for phase-locking and an
output buffer amplifier. This MMIC uses Mimix Broadband’s 2
µm
GaAs HBT 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.
