CHV2241
K-band Oscillator with integrated Q-band Harmonic
Mixer
GaAs Monolithic Microwave IC
Description
The CHV2241 is a monolithic multifunction
proposed for frequency generation and
transposition. It integrates a K-band oscillator, a
Q-band harmonic mixer and buffer amplifiers.
For performance optimisation, an external port
(ERC) allows a passive resonator coupling to
the oscillator (at half output frequency). 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.
