United Monolithic Semiconductors 

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.
