A chain coil and a capacitor having sufficiently large impedance for the high frequency signal flowing through the PIN diode are connected to both ends of the N diode array and the PIN diode array, and the other end of the chain coil is used as the bias terminal of the PIN diode. In a PIN diode switch circuit with the other end of the capacitor as a high-frequency signal terminal, the impedance of the capacitor with respect to the frequency of the high-frequency signal to be transmitted is made sufficiently large compared to the characteristic impedance of the transmission line, and the capacitor and the PIN A PIN diode switch characterized in that the characteristic impedance is increased in order to match only the transmission line between the diode and the transmission line.
