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.

Voltage controlled oscillator module with ball grid array resonator

A synthesizer module/oscillator assembly includes a voltage controlled oscillator with a coaxial resonator. In one embodiment, the module measures 20.3 mm&#xd7;14.8 mm&#xd7;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.

Coaxial resonator based voltage controlled oscillator/phased locked loop synthesizer module

A module for a surface acoustic wave oscillator includes a substrate having a top surface, a bottom surface and peripheral side faces. Several castellations are located about the outer peripheral side faces thereof. The castellations form an electrical connection between the top and bottom surfaces of the substrate. Connection pads are mounted on the top surface and are adapted for connection to the castellations. An oscillator circuit and a surface acoustic wave device are mounted on the top surface and connected to the connection pads. A cover is mounted over the substrate and has at least one tab adapted to be fitted within a respective one of the castellations. The overall module with the cover has a dimension of approximately 5 mm in width, 7 mm in length, and 2.7 mm in height.
