RFIC Solutions Inc. Negative Resistance Generator Description . Preliminary Datasheet GRV03 Functional Diagram . The GRV03 is 14 to 21 GHz: broadband Negative Resistance Generator designed using 2 um HBT Technology. The GRV03 consumes only 4 mA current and the die area is very small. The phase noise of the oscillator can be improved using external high Q resonator. The buffer Amplifier is followed by the VCO to improve the output power.
