BROADCAST RECEIVER FOR MOBILE COMMUNICATION TERMINAL

摘要

A broadcast receiver for mobile communication terminal capable of preventing any resource frequency deviation from occurring in an antenna tuner circuit due to an unwanted voltage induced in a reception antenna, thereby receiving any mobile broadcast of high sensitivity. In a broadcast receiver for mobile communication terminal that has a reception antenna and an antenna tuner circuit connected thereto, the resource frequency of the antenna tuner circuit is varied, whereby the reception antenna can receive a broadcast signal tuned to the resource frequency. The antenna tuner circuit has an unwanted voltage suppressing means for suppressing any unwanted voltages that are induced by a transport signal outputted from a transmission antenna of the mobile communication terminal being inputted to the reception antenna and occur due to the rectification of a variable capacitance diode.
