RFIC Solutions Inc. VCO Description . Preliminary Datasheet GRV02 Functional Diagram . The GRV02 is 10 to 15 GHz; broadband VCO designed on 2 um GaAs HBT Technology. The resonator part is split on-chip inductor and off-chip Varactor. The VCO consumes only 3.5 mA current and the layout is very tiny. The phase noise of the GEV03 can be improved using the high Q off chip resonator. The buffer Amplifier is followed by the VCO to improve the output.
