摘要: A voltage controlled oscillator includes a VCO chip that is a monolithic circuit with a Gunn diode and varactor diode intercoupled by a resonant circuit. A detector/discriminator/power divider chip is coupled to the VCO chip through a directional coupler and is a monolithic circuit having a pair of discriminator diodes and amplitude detector diode on a semi-insulating substrate with associated circuit components. Connected-together electrodes of the discriminator diodes are connected to one output of the power divider. An electrode of the amplitude detector diode is connected to the other output of the power divider. Stagger-tuned resonant circuits are coupled to the other electrodes of the discriminator diodes. Conducting portions forming low pass filters couple the amplitude detector diode and the discriminator detector diodes to respective outputs. The outputs of the discriminator and amplitude detector are coupled to respective inputs of an analog divider that provides a ratio signal that is coupled to the - input of a differential amplifier. The + input of the differential amplifier receives a frequency designating potential. The output of the differential amplifier is coupled to the varactor diode.
