Claim:
1. An impedance matching network having a first impedance matching terminal and a second impedance matching terminal, the impedance matching network comprising: a first parallel reactive network connected to the first impedance matching terminal of the impedance matching network, the first parallel reactive network comprising a plurality of parallel branches each connected the first impedance matching terminal and a reference potential, each parallel branch comprising one or more reactive elements connected in series, wherein one parallel branch from among the plurality of parallel branches comprises two series—connected elements; a series reactive network having a first terminal and a second terminal, the series reactive network comprising at least an inductor, the first terminal of the series reactive network being connected to a node joining the two series—connected elements of the one parallel branch of the first parallel reactive network; and a second parallel reactive network connected to the second impedance matching terminal of the impedance matching network, the second parallel reactive network comprising a plurality of parallel branches each connected between the second impedance matching terminal and the reference potential, each parallel branch comprising one or more reactive elements connected in series, the second parallel reactive network being connected at a node to both the second impedance matching terminal and to the second terminal of the series reactive network, wherein the impedance matching network is configured to match an impedance at the first impedance matching terminal of the impedance matching network to a variable impedance at the second impedance matching terminal of the impedance matching network, and wherein the second parallel reactive network is configured to provide a harmonic termination.
