Abstract: A four-port RF hybrid coupler includes a substrate having first and second primary traces and first and second coupled traces on a first surface thereof. The first coupled trace has: (i) a first end configured to provide a first degree of RF coupling to a first end of the first primary trace when the RF hybrid coupler is active, and (ii) a second end configured to provide a third degree of RF coupling to a second end of the second primary trace when the RF hybrid coupler is active. The second coupled trace has: (i) a first end configured to provide a fourth degree of RF coupling to the first end of the second primary trace when the RF hybrid coupler is active, and (ii) a second end configured to provide a second degree of RF coupling to the second end of the first primary trace when the RF hybrid coupler is active. First and second energy cancellation circuits are also provided. The first energy cancellation circuit includes a first termination coupler having an input port electrically coupled to an end of the second coupled trace, and the second energy cancellation circuit includes a second termination coupler having an input port electrically coupled to an end of the first coupled trace.
