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