Abstract
A synthesizer module/oscillator assembly includes a voltage controlled oscillator with a coaxial resonator. In one embodiment, the module measures 20.3 mm×14.8 mm×3.9 mm and the coaxial resonator is positioned on the circuit board of the module between a phase locked loop integrated circuit and a main section of the voltage controlled oscillator. The phase locked loop circuit includes a loop filter and is adapted to receive the frequency signal generated by the voltage controlled oscillator and generate an adjusted frequency signal.
