Description
The CHV2242a 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
