Multiplier
Microphase’s multiplier units rely on the impulse generating characteristics of step recovery diodes to produce a comb spectrum at 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, inexpensive, narrowband, spectrally pure signal generator based on a low input frequency. Multiple frequencies, switch selectable, single output port or multiple output ports are available as required.
