CHV2240
RoHS COMPLIANT
Multifunction K-band VCO and Q-band Multiplier
GaAs Monolithic Microwave IC
Description
The CHV2240 is a monolithic multifunction
proposed for frequency generation at
38GHz. It integrates a K-band Voltage
Controlled Oscillator, a Q-band frequency
multiplier and buffer amplifiers. For
performance optimisation, an external port
(ERC) allows a passive resonator coupling
to the oscillator (at half output frequency).
This chip has been especially designed to
be coupled to a high Q dielectric resonator.
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.
