  • COMPACT HYBRID COUPLERS HAVING STRONG BROADBAND COUPLING FOR BASE STATION ANTENNA SYSTEMS
    Publication number: 20240204384
    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.
