General Description
Mimix Broadband's 7.4-8.6 GHz GaAs HBT VCO is a fully
integrated oscillator MMIC with on-chip tuning diode and
resonator. This design is based on a cross coupled differential
pair with on-chip buffer amplifier and output balun. The use of
a high-Q resonator structure and integrated varactor diodes
results in optimum phase-noise performance. This MMIC uses
Mimix Broadband's 2 um GaAs HBT device model technology
to ensure low flicker (1/f ) noise and high reliability. 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.
