电视调谐器模块具有安装在外部电路板上并具有调谐器芯片的内部电路板的屏蔽壳体

Television tuner module having a shielded housing mounted on an outer circuit board and having an inner circuit board with a tuner chip
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.
