CHU2277A

CHU2277a RoHS COMPLIANT W-band Multifunction : Multiplier / MPA GaAs Monolithic Microwave IC Description The CHU2277a is a W-band monolithic multifunction which integrates a frequency multiplier, a four-stage amplifier and a power divider. The frequency multiplier is based on an active transistor and allows to operate at low input level with a reduced power consumption. This chip provides two outputs at 77GHz, the main one is for the transmission path and the auxiliary one for the receiving mixer (s) LO signal. All the active devices are internally self biased. This chip is compatible with automatic equipment for assembly. The circuit is manufactured with the P-HEMT process : 0.15µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form.
