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). CHV2240 has been especially designed to be coupled to a high Q dielectric resonator.

All the active devices CHV2240 are internally self biased.

CHV2240 is manufactured with the PHEMT process : 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography.

CHV2240 is available in chip form.
