CHV2243A_15 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 pHEMT
based Schottky diode is used as varactor. All
the active devices are internally self biased.
The circuit is manufactured with the pHEMT
process 0.25µm gate length, via holes through
the substrate, air bridges and electron beam
gate lithography.
It is available in chip form.
