General Description
Mimix Broadband's 14.7-15.7 GHz GaAs HBT VCO is a fully
integrated oscillator MMIC with on-chip frequency doubler
and divide-by-8 prescaler (w.r.t RFout). This design is based on
a cross coupled differential pair with on-chip tuning diode and
resonator. The use of a high-Q resonator structure and
integrated varactor diodes results in optimum phase-noise
performance, whilst the integration of frequency doubler and
prescaler reduce application complexity and time-to-market.
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.

recommended to keep channel temperature as low as
possible for maximum life.
