Linearity in solid state microwave voltage tuned oscillators
Abstract
A computer program written in BASIC is presented for predicting the linearity profile of solid state microwave voltage tuned oscillators (VCO). The critical VCO parameters are discussed, including frequency and power pushing and pulling and the environmental effects on power and frequency, controllable by external devices. Power and frequency interaction is explored, as are the spectral response, the phase noise short term stability, and the tuning bandwidth, which when narrow enhances the linearity. Attention is given to post tuning drift, settling time, and CW response as facets of the operational feature that VCO output/time response follows the input voltage as a time dependent function. Reasons for discrepancies in voltage/response interaction are investigated. Linearity is characterized in terms of basic and equivalent circuits, varactor tuning ranges, and the linearity program, written for implementation in any computer that uses BASIC.
