As the implementation of 5G and 5G NR (New Radio), SATCOM internet connectivity and direct to home (DTH) broadcast quickly gains momentum, new high-performance devices, systems, and test and measurement equipment are needed to support the ultra-high frequencies and high data rates that technologies like mmWave, multi-input multi-output (MIMO) antenna and RF front-end technology, beam-forming and full duplex demand.

This 90 & 180 Degree Hybrid Coupler Primer discusses where the two devices used for different purposes. Hybrid and directional couplers are 4-port passive devices based on the same operational principles but with different coupling levels between ports.
