ABSTRACT:
An oscillator includes an amplifier having an input and an output and a feedback circuit disposed between the input and the output of the amplifier. The feedback circuit includes a plurality of resonators and a pair of switches. Each switch includes a first port and multiple connectable ports, the multiple connectable ports of each switch connected to a corresponding one of the plurality of resonators. The feedback circuit further includes a voltage-controlled phase shifter disposed in series with the switches. The oscillator further includes a discriminator circuit, responsive to signals from the feedback circuit, for providing a control signal to the voltage-controlled phase shifter for degenerating low frequency noise within the oscillator. With such an arrangement, high Q low noise resonators can be switched in and out of the circuit thus providing improved phase noise performance at high power levels with the desirable frequency agility required for a microwave oscillator.
