High frequency tuner module

Abstract

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.

Dependencies are inferred from the claim text.
