Disclosed is a high frequency tuner module, including: a circuit component; signal lines; a GND line; and a multilayer board formed by laminating a plurality of layers, wherein the circuit component is placed on a top layer surface of the multilayer board; the signal lines and the GND line are formed inside the multilayer board; and among the signal lines, high frequency signal transmitting signal lines to transmit a high frequency signal are formed on a single layer inside the multilayer board.

High frequency tuner module and tuner module

An RF input portion is formed on a printed circuit board and is operable to input a high-frequency signal received by an antenna device. An electronic component is mounted on the printed circuit and is operable to process the input high-frequency signal. The RF input portion has a specific pattern adapted to be electrically interchangeably connectable with a plurality of types of connections.

Tuner module

Disclosed is a high frequency wave tuner module including a circuit board having an approximately rectangular shape, which is made of ceramic material and a shield cover to shield an interfering wave by covering a circuit part mounted on a board surface of the circuit board, and a position of the shield cover in a height direction with respect to the board surface is determined by fixing the shield cover to the board surface at four corner positions of the circuit board, and a position of the shield cover in a board surface direction with respect to the circuit board is determined by engaging at least two side walls of the shield cover which extend in a thickness direction of the circuit board, with end surfaces of the circuit board, which correspond to the two side walls.

High frequency tuner module

A circuit board has a first face and a second face opposite to the first face. An electronic component is mounted on the second face. An insulative sheet is disposed between the first face of the circuit board and an antenna and having an electromagnetic shielding property.

Antenna device

Tuner

An antenna unit includes a feeding componentand a metal plateon which the feeding componentis mounted. The feeding componenthas an attaching membermade of resin to support a feeding line against the metal plate. The metal platehas a pair of cut and raised partsat both ends thereof while the attaching memberhas a pair of locking hooksat both ends thereof. The locking hooks are partly inserted into the cut and raised parts and thereby the feeding component is attached to the metal plate without projecting any parts of the attaching member from a rear surface of the metal plate.

Antenna unit and feeding component

A feeding componenthas a wire (or a feeding line)and an attaching membermade of resin. The attaching memberprovides wire receiving groovesandto receive and support the wire. At least one pair of wire holding partsare formed on inner wall defining the wire receiving groovesand. The wire holding partsof each pair are opposite to each other and inclined to narrow a width of the wire receiving grooveorwith increasing proximity to an upper side of the wire receiving grooveor. The wire holding partshold the wireput into the wire receiving groovesand
