چکیده
A MMIC colpitts oscillator in push-push configuration is presented using InGaP/GaAs HBTs. The output at the second harmonic enhances the frequency range while preserving the well-known advantages of the Colpitts concept. Moreover, additional features like enhanced load-pull immunity and inherent frequency divider functionality are included. The MMIC VCO reaches state-of-the-art phasenoise performance in X-band.
