APITech's Series 95 Comb Generators use a Step Recovery Diode (SRD) to generate very narrow voltage spikes; these in turn produce an output frequency spectrum rich in harmonics. The spacing between the signals is equal to the source that drives the SRD which, in most cases, is a stable crystal oscillator. The crystal oscillator is normally internal, however, an external signal can be used to drive the SRD.
Designing and producing our improved phase noise comb generators in-house allows API Technologies to offer improved Spurious response and better selectivity.
