Tuner structure and cable modem tuner using the same

摘要

The tuner structure of the present invention includes: a circuit board on which electronic circuit components such as transistors, resistors and feedthrough capacitors have been mounted; a chassis angle including a pair of shorter chassis sides, a pair of longer chassis sides and a central chassis angle plane; a shield cover; and an input connector is provided. In the tuner structure, when an outer diameter of a surface of the input connector to be contacted with one of the pair of shorter chassis sides of the chassis angle and a thickness of the chassis angle are denoted by A and B, respectively, a relationship A > B is satisfied. <IMAGE>
