✦ Synopsis
Theoretical analysis of the stability conditions of the steady-state operation modes and tuning bandwidth characteristics of bipolar self-biased varactor-controlled oscillator (VCO) with two-coupled resonant circuits are presented. The recommendations at the choice of the circuit and varactor parameters for a linearization of the wideband tuning frequency characteristics under free-running stable oscillation conditions are given. Highly linear octave-band tuning operation was found to be possible using hyperabrupt varactors in two-coupled resonant circuits VCO. Numerical and experimental results verify the validity of the design approach described.
