Abstract
A method of providing an impedance match for an integrated semiconductor circuit to other microwave elements is provided by allowing the selection of one of a plurality of impedance matching ratios between the circuit and other elements. The tunable impedance match comprises a microwave impedance transformer with at least a single primary winding, and a plurality of secondary windings, wherein the winding configuration is determined by an electrical switching apparatus allowing the secondary windings to be connected in series, parallel and combinations thereof to provide the required impedance matching. The method allows for both dynamic matching of an integrated semiconductor circuit for increased efficiency, and hence reduced power consumption, and directly matching said circuit to high impedance antennae etc.
