A device used to generate a signal which is beat against the signal of interest to mix it to a different frequency. Power is supplied by solid-state Gunn oscillator which are phase locked. The output is used to drive a Schottky diode frequency multiplier. Several local oscillators can be strung in series to form a so-called "LO chain."
