A semi-monolithic wideband VCO with output power control capability using an active power splitter

Abstract

A one-octave bandwidth semi-monolithic VCO (voltage-controlled oscillator) which has output power control capability has been developed using an active power splitter. This novel VCO exhibits an output power of 13.6+or-1.2 dBm and an output power control variation of 30 dB. The output power match between two output ports is less than 0.6 dB over 8.8 to 17.6 GHz. This semi-monolithic approach provides significant performance, cost, reliability, reproducibility, and manufacturing cycles. This VCO is useful for such applications as multichannel systems and frequency synthesizers.<>
