Spectrum Microwave 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. Examples of the spectrum for a number of
comb generators are included on the reverse side of
this fact sheet. The crystal oscillator is normally
internal; however, an external signal can be used to
drive the SRD.
If only certain combline signals are required for a
particular application, a filter tuned to the desired
combline must be used.
Comb Generators have several applications. They are
commonly used as Built-in-Test (BIT) oscillators to
calibrate receivers; other uses are in Phase Locked
Loops (PLL), Jammers, Antenna Testing, Linearizing
Voltage Controlled Oscillators, etc.
