Patent ID: 7183875

Claim:
A high frequency switching component for being connected to a transmission circuit, a reception circuit, and an antenna, the high frequency switching component comprising: a multilayer circuit board including a plurality of insulative layers; a high frequency switch including an inductor, a capacitor and a diode for switching either to a state in which the transmission circuit is connected to the antenna or a state in which the reception circuit is connected to the antenna; a plurality of terminals including a transmission circuit terminal to be connected to the transmission circuit, a reception circuit terminal to be connected to the reception circuit, an antenna terminal to be connected to the antenna, and a ground terminal, each of the transmission circuit terminal, the reception circuit terminal, the antenna terminal and the ground terminal being disposed on a surface of the multilayer circuit board; a first inductor for eliminating an electrostatic surge provided between the reception circuit terminal and a capacitor provided adjacent to the reception circuit terminal; and a second inductor for eliminating an electrostatic surge provided between the transmission circuit terminal and a capacitor provided adjacent to the transmission circuit terminal.
