CHV2243
Fully Integrated Q-band VCO
based on Ku-band Oscillator and Q-band Multiplier
GaAs Monolithic Microwave IC
Description
The CHV2243 is a monolithic multifunction
for frequency generation. It integrates a
Ku-band oscillator with frequency control
(VCO), a Q-band frequency multiplier and
buffer amplifiers. The VCO is fully
integrated. On chip P-HEMT based
Schottky diode is used as varactor. All the
active devices are internally self biased.
The circuit is manufactured with the P-
HEMT process : 0.25µm gate length, via
holes through the substrate, air bridges
and electron beam gate lithography.
It is available in chip form.
