Patent ID: 7324060

Claim:
An RF power divider circuit for unequally dividing an input signal into first and second signal components of unequal power, comprising: a single input port; first and second output ports; a termination port, wherein the first and second output ports are separate and distinct from said termination port; a combination of a plurality of quarter wave transformers and a plurality of resistors coupled between said input port, said termination port and said first and second output ports, said plurality of quarter wave transformers comprising a dielectric substrate and a conductor strip pattern formed on the dielectric substrate, wherein said combination of a plurality of quarter wave transformers and a plurality of resistors comprises: a first quarter wave transformer connected between said input port and a first circuit node, a second quarter wave transformer connected between said first circuit node and a second circuit node, a third quarter wave transformer connected between said first circuit node and a third circuit node, a first resistive element connected between said second and said third circuit nodes, a second resistive element connected between said second circuit node and said termination port, a fourth quarter wave transformer connected between said termination port and a fourth circuit node, a fifth quarter wave transformer connected between said second circuit node and said fourth circuit node, a sixth quarter wave transformer connected between said fourth circuit node and said first output port, a seventh quarter wave transformer connected between said third circuit node and a fifth circuit node, and an eight quarter wave transformer connected between said fifth circuit node and said second output port; and a termination resistor connected between said termination port and ground, wherein an input signal at said input port propagates through said power divider circuit and said is divided into the first and second signal components at said first and second output ports and a termination signal component through said termination resistor.
