Antenna switch circuit and high frequency module having the same |
摘要 |
An object of the present invention is to provide an antenna switch circuit that effectively reduces signal leakages at a cross point even at higher operating frequencies and a high frequency module containing said antenna switch module. The antenna switch circuit comprises: a high frequency signal line to transmit a transmitting signal to be input to transmitting terminals to an antenna terminal and also to transmit a receiving signal to be input to the antenna terminal to receiving terminals; switches that are connected in the middle of the high frequency signal line between transmitting terminal and antenna terminal; switches that are connected in the middle of the high frequency signal line between receiving terminal and antenna terminal; and signal lines to transmit control signals for controlling turning on and off of the switches.
