<p>Series resonance circuits (SR1, SR2) composed of series circuits of inductors (LN1, LN2) and capacitors (CN1, CN2) are shunt connected to a line. Diodes (D1, D2) serving as switching elements are inserted between the grounded ends and the ground. The connection nodes between the grounded ends of the series resonance circuits (SR2, SR2) and the diodes (D1, D2) are grounded in a high-frequency manner through inductors (LN11, LN22) for frequency characteristic change-over. A matching circuit (MC) composed of T circuits of LCL is inserted between the series resonance circuits (SR1, SR2). The other terminals of the series resonance circuits (SR1, SR2) than the grounded ends of series resonance circuit (SR1, SR2) are connected to the input and output terminals (P1, P2).</p> |
