ABSTRACT:
A voltage controlled oscillator module assembly (300) minimizes microphonics in a low profile package. Included within the module (300) are a substrate (302), VCO circuitry (308), and a ground shield (314) encapsulating the VCO circuitry. Included within the VCO circuitry (308) is at least one resonator (310) which is solderable on at least two of its surfaces. One surface of the resonator (310) is soldered to the substrate (302) while another surface of the resonator is soldered to the shield (314). An improved ground is thus provided to the resonator (310) which reduces the occurrences of microphonics while providing a low profile package for the module (300).
