step-recovery diode

step-recovery diode

[′step ri¦kəv·rē ′dī‚ōd]
(electronics)
A varactor in which forward voltage injects carriers across the junction, but before the carriers can combine, voltage reverses and carriers return to their origin in a group; the result is abrupt cessation of reverse current and a harmonic-rich waveform.

The LO comprises a 100 MHz crystal oscillator and amplifier driving a step-recovery diode comb generator, and exhibits a phase noise level that is at least 3 dB below the system noise specification.
An internal step-recovery diode (SRD) multiplies the 142.875 MHz input signal, which is supplied by the external crystal oscillator, by 160.
This frequency is then multiplied and filtered to 14 GHz by a single step-recovery diode multiplier, and finally multiplied again to 42 GHz by means of a balanced X3 Schottky diode multiplier.
Sometimes a step-recovery diode (SRD) is used to generate a comb of output frequencies as an LO source.
