CHV2244A
PRELIMINARY
Fully Integrated HBT Q-band VCO
based on Ku-band Oscillator and Q-band Multiplier
GaAs Monolithic Microwave IC
Description
The
CHV2244A
is
a
monolithic
multifunction for frequency generation. It
integrates a Ku-band oscillator with
frequency control (VCO), a Q-band filter
and buffer amplifiers. The VCO is fully
integrated on HBT process. On chip base-
collector diodes are used as varactors. Two
tuning ports are available with different
tuning sensitivity. All the active devices are
internally self biased.
The circuit is manufactured on HBT
process: 2µm emitter length, via holes
through the substrate and high Q passive
elements.
