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.
