Patent ID: 7616934

Claim:
A circuit comprising: a substrate; an input port integrated within the substrate for receiving an input RF signal; an output port integrated within the substrate supporting each of a predetermined set of available impedance characteristics for providing an output RF signal based on the input RF signal; a first electrical track integrated within the substrate for transmission of the input RF signal; a second electrical track integrated within the substrate for being inductively coupled to the first electrical track; a third electrical track integrated within the substrate for being inductively coupled to the first electrical track; at least a switch integrated within the substrate, the at least a switch operable between a first state and a second state, the at least a switch for in the first state resulting in the second electrical track and third electrical track electrically coupled in a first configuration and wherein, in the first state, the first electrical track and the second and third electrical tracks are electrically coupled between the input port and the output port for providing a first impedance characteristic from the predetermined set of available impedance characteristics at the output port; and for in the second state resulting in a the second and third electrical track electrically coupled in a second configuration, and wherein, in the second state, the first electrical track and the second and third electrical tracks are electrically coupled between the input port and the output port for providing a second other impedance characteristic from the predetermined set of available impedance characteristics at the output port.
