A reduced-size VCO/PLL module including a circuit board having a plurality of components positioned, mounted and interconnected thereon in a manner allowing the same to fit in a 10.5 mm x 14 mm x 2.9 mm package. In one embodiment, an inner lid encloses the VCO portion of the module. In all embodiments, an outer lid is adapted to cover all of the components on the circuit board of the module. The inner and outer lids include tabs adapted to be fitted within respective apertures defined in the board. In a preferred embodiment, the VCO portion occupies one side of the module while an integrated circuit chip and a loop filter occupy an opposite side of the module. |
