ABSTRACT:
There are provided a transmission/reception switching circuit which is small in insertion loss and harmonic distortion and allows an increase in the output power of a power amplifier and an electronic component for communication on which the transmission/reception switching circuit is mounted. As an element composing a transmission/reception switching circuit in a wireless communication system, series-connected FETs or a multi-gate FET are used in place of a diode. Gate resistors connected between the individual gate terminals and a control terminal are designed to have resistance values which become progressively smaller from the gate to which a highest voltage is applied toward the gate to which a lowest voltage is applied.
