This multiplier relies on the impulse generating characteristics of step recovery diodes to produce a comb spectrum at multiples of the input frequency. The desired harmonics are filtered to produce spectrally pure low phase noise output signals that are integer multiples of the input frequency. Typically, an input amplifier is used to provide the correct operating level for the step recovery diode and optionally an output amplifier may be added to increase the output power for high order multiplications. The result is a compact, narrowband, spectrally pure signal generator based on a low input frequency. Multiple frequency, switch selectable, single output ports or multiple output ports are available as required.
