CHV2243A Datasheet, PDF (1/6 Pages) United Monolithic Semiconductors – Fully Integrated Q-band VCO based on Ku-band Oscillator and Q-band Multiplier

CHV2243a
RoHS COMPLIANT
Fully Integrated Q-band VCO
based on Ku-band Oscillator and Q-band Multiplier
GaAs Monolithic Microwave IC
Description
The CHV2243a 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.
