Abstract

Portable UHF transceivers typically require minimal current drain frequency converters to multiply the frequencies generated by crystal controlled oscillators up to the UHF band. The step recovery diode (SRD) provides an approach to frequency multiplication that requires no d.c. bias and hence minimizes battery drain. This thesis compares the SRD to the more conventional varactor and analyzes SRD device physics and characteristics. SRD operation is explained in terms of the conduction and depletion intervals. The rapid transition from the conduction to the depletion mode allows the SRD to generate high order harmonics of the input frequency. A step-by-step design procedure for a series mode frequency multiplier is presented and empirical observations are used to help explain multiplier operation. The jump phenomena and hysteresis effects previously unexplained in relation to SRD multipliers are explored. Finally, it is shown that the SRD can function as a parametric amplifier.
