Abstract
A voltage controlled oscillator (VCO) assembly and module incorporating a ball grid array resonator as part of the tank circuit of the voltage controlled oscillator. The VCO module preferably incorporates at least an oscillator circuit, the tank circuit, and an output buffer stage circuit all defined by a plurality of interconnected electrical/electronic components including the ball grid array resonator which are mounted to a printed circuit board. In another embodiment, the oscillator assembly also includes a phase-locked loop circuit defined at least in part by an integrated circuit mounted to the printed circuit board.
