SiGe Integrated mm-Wave Push-Push VCOs with Reduced Power Consumption
For use in automotive radar applications we have designed and fabricated several push-push VCOs within the frequency range 67 to 75 GHz. In this paper we present one of these oscillators which can be tuned from 71.3 GHz to 75.8 GHz. In this tuning range the measured output power is 3.5 it 0.4 dBm with an DC to RF efficiency /spl eta/ = 1.6
