Classification: CPC H | IPC H

Claim 0:
1. Circuitry comprising:
a first resonant radio frequency conductive path comprising a first transmission line between a first node and a third node;
a second resonant radio frequency conductive path comprising a second transmission line between a second node and the third node;
an internode radio frequency conductive path comprising a third transmission line between the first node and the second node;
a shunt resonant element coupled to the third node and shared by the first resonant radio frequency conductive path and the second resonant radio frequency conductive path; and
a phase shift element for introducing a relative phase shift to the first resonant radio frequency conductive path relative to the second resonant radio frequency conductive path, wherein the first transmission line and the second transmission line comprise respective branches from the third transmission line with the first transmission line, but not the second transmission line, comprising the phase shift element.
