Abstract
Described systems and methods allow the manufacture of compact television (TV) tuner modules comparable in size to standard RF connectors. In some embodiments, a compact TV tuner module (tuner can) includes a metallic housing mounted on an external printed circuit board (PCB), a radio-frequency (RF) connector, an internal PCB within the housing, and a bare-silicon TV tuner chip centrally mounted on a side of the internal PCB facing away from the RF connector, directly opposite a central contact made directly a central pin of the RF connector and a central area of the internal PCB. A major dimension of a shielded internal volume enclosed by the housing is less than 150% of an outer shell of the RF connector, and may be about equal to or slightly larger than the diameter of the RF connector.
