Abstract
A VCO tunable over a frequency range of 6.94 to 19.22 GHz in 20 V has been achieved by broadbanding a hyperabrupt varactor tuned bipolar oscillator. This was accomplished by introducing variable phase feedback in the form of a second hyperabrupt junction-varactor diode. The high operating frequency was attained by using a doubling mode circuit.
