Description

The CHV2242a is a monolithic multifunction for frequency generation. It integrates a Ku-band oscillator with frequency control (VCO), a Qband 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 CHV2242a, based on a P-HEMT, is used as varactor. All the active devices are internally self biased.

CHV2242a is manufactured with the P-HEMT process : 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography.

CHV2242a is available in chip form.
