PROBLEM TO BE SOLVED: To provide an antenna switch module in which the number of resistors to be packaged in respective high frequency switch parts can be decreased. SOLUTION: In an antenna switch module 1a provided with diodes D1-D6 parallel connected to mutually invert respective high frequency switch parts 4, 5 and 6 on the side of an antenna electrode 2 and voltage terminals VC1, VC2 and VC3 of a voltage controlled circuit part connected on the anode side of any one of the diodes D1-D6 connecting a cathode thereof on the side of the antenna electrode 2 and capable of dealing with dual bands, the other terminal of one shared resistor R1 connecting one terminal is respectively connected to the cathode sides of the diodes D1-D6 on the other side not to connect the voltage terminals VC1, VC2 and VC3. Thus, the respective high frequency switch parts 4, 5 and 6 can share one resistor. COPYRIGHT: (C)2003,JPO
