摘要： The present invention has for its object to provide a matching circuit with multiband capability which can be reduced in size, even if the number of handled frequency bands rises. The matching circuit of the present invention comprises a load having frequency-dependent characteristics, a first matching block connected with one end to the load with frequency-dependent characteristics, and a second matching block formed by lumped elements connected in series to the first matching block. And then, when a certain frequency band is used, matching is obtained with the series impedance of the first matching block and the second matching block. When a separate frequency band is used, a π-type circuit is constituted by connecting auxiliary matching blocks to both sides of the second matching block. Next, at the same frequency, by taking the combined impedance of this π-type circuit and a load whose characteristics do not depend on the frequency to be Z0, the influence of the second matching block is removed.

摘要： First, second and third matching parts 110, 120, and 130 are connected in series between a circuit element 199 whose impedance has a frequency characteristic and a circuitry 198 having a constant impedance. The second matching part 120 has the capability of converting impedances. The first matching part 110 operates as an element having reactance values according to any of frequency bands selected by exclusive switching between on and off of switches 118, 119 and the third matching part 130 operates as an element having reactance values according to any of the frequency bands selected by switching between on and off of a switch 133, thereby providing matching in each frequency band. A seventh reactance circuit 131 is configured on the basis of an interdependence relation with the configuration of a fifth reactance circuit 115 and an eighth reactance circuit 132.
