Abstract
A variable frequency oscillator circuit for generating an oscillating signal of a desired frequency, comprising a fixed frequency oscillator; one or more frequency dividers, arranged to receive the output of the fixed frequency oscillator and generate a signal with a divided frequency; and one or mixers, arranged to mix the outputs of the one or more frequency dividers to generate the oscillating signal of the desired frequency. The variable frequency oscillator circuit is arranged to modify the operation of the one or more mixers to suppress any unwanted signals in the generated oscillating signal.
