Abstract

A voltage controlled oscillator module (100) (400) provides tuning capability for the VCO in a shielded environment. The module includes a trimmable capacitor (110) (410) having metal plates (112, 114), (412, 414, 416) capacitively coupled through the substrate. One of the metal plates (114) (416) is a trimmable plate which can be trimmed to tune the VCO frequency. The trimmable metal plate (114) (416) remains exposed on the bottom surface (108) (408) of the substrate (104) (404) so that the frequency of the VCO can be tuned while the reminder of the oscillator circuitry (102) (402) on the top surface (106) (406) is encapsulated by a ground shield (116) (418).
