A circuit arrangement connects a plurality of frequency multiplier stages, each producing a different output frequency, and only one of which operates at a specific time, to a common fundamental frequency generator. Each of a plurality of switching diodes couples the input of a corresponding one of the frequency multiplier stages to the fundamental frequency generator. Each of a plurality of bandpass filters is tuned to a different corresponding harmonic and each couples the output of corresponding one of the frequency multiplier stages to a common output terminal. A current supply is connected to the switching diodes for supplying current to the fundamental frequency generator via the switching diode of the operating frequency multiplier stage.
