Abstract
An oscillator having two oscillation circuits with widely different frequencies with a common passive switched output circuit. Each oscillator circuit includes a transmission line inductive impedance between the oscillator output and ground. The inductive impedances are selected to be open at the operating frequency of the associated oscillator circuit and a short or a low impedance at the frequency of the other oscillator circuit. Each inductive impedance forms a portion of an impedance matching pad for the other oscillator circuit.
