An impedance matching network having a plurality of reactance elements is disclosed. Each of the plurality of switching circuits comprises a first node and a second node; a first diode having an anode coupled to the first node and a cathode coupled to the second node; a second diode having an anode to couple to the second voltage line and a cathode to couple to the first node; and a transistor having a first, second, and control terminals. Each of the plurality of reactance elements is switched into the impedance matching network when the transistor in the respective one of the plurality of switching circuits is on and switched out after the transistor in the respective one of the plurality of switching circuits is off.
