CHV2242c
RoHS COMPLIANT
Q-band VCO based on Ku-band Oscillator
and Q-band Multiplier
GaAs Monolithic Microwave IC
Description
The CHV2242c 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.
For performance optimisation, two external
ports (ERC1 and ERC2) allow a passive
resonator coupling to the oscillator (at one third
of output frequency). On chip Schottky diode,
based on a P-HEMT, 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.
