Multi-octave FET voltage controlled oscillators for EW applications

摘要

The advent of more sophisticated electronic warfare andncountermeasure systems with a variety of complex roles has resulted innan increased requirement for high performance ultra broadband voltagencontrolled oscillators (VCO). Most military systems operate within the 6nto 18 GHz frequency range using up to three separate VCOs, to cover thenfull band. Such an arrangement is somewhat cumbersome as it involvesnswitching coupling and linearising the outputs of three VCOs thusnincreasing the size, weight and cost of any system. For this reasonnPlessey Three-Five Group Limited have developed a multi-octave FET VCOndesign in the common module format (measuring 6×12 mm) with thenultimate aim of covering the full 6 to 18 GHz band
