Antenna switch circuit, and composite high frequency part and mobile communication device using the same
摘要：
First and second through-side field effect transistors are connected between first and second high frequency signal input/output terminals, and an antenna, respectively. The first and the second high frequency signal input/output terminals are connected with one end of the first and the second shunt-side field effect transistors, respectively. A series resonant circuit including a shunt capacitor and a bonding wire is connected between the other end of the first and the second shunt-side field effect transistors, and a ground.
摘要（中）：
