Frequency Synthesizer Design Toolkit

This software is aimed at practitioners wishing to gain a broader systems-based perspective of phase-locked loops. It allows quick and efficient solving of filter and attenuator design problems often occurring in the design of frequency synthesizer haedware and related to RF systems. The software is divided into four modules: "White" provides a highly-integrated lumped-element bandpass filter design program, "COMB" allows the fast design and analysis of microstrip combline filters, "SRD" automatically designs high-performance step-recovery diode multipliers, and "RPAD" considers all resistor permutations and their associated S-parameter quantities.
