Fast tuning voltage controlled oscillators
Abstract
It is emphasized that just as the fast tuning voltage controlled oscillator (VCO) is the key to the highly agile ECM system, the varactor diode is the key to the VCO. This paper examines such VCO parameters as slew speed, settling time and post tuning drift, and presents a detailed analysis of the relationship between an ECM system, the VCO and the varactor. Attention is given to the typical specifications of a fast tuning VCO and comparisons are presented between closed and open loop responses for tuning steps from 4 to 8 GHz and from 6 to 8 GHz.
