A 3 dB, 90° hybrid coupler is a four-port device that is used either to equally split an input signal with a resultant 90° phase shift between output ports or to combine two signals while maintaining high isolation between the ports. This 3 dB, 90° hybrid couplers is equipped with SMA-Female connectors and a rugged aluminum housing coated with a RoHS compliant iridite finish for long lasting, reliable performance. It offers low insertion loss and excellent VSWR.
 

Common Applications: Carriers are often faced with the challenge of adding next generation services while trying to keep CAPX equipment costs low. An economical solution to this problem is to combine two transmitters with a hybrid coupler to share one antenna, thus freeing up another antenna for the overlay. The hybrid coupler provides excellent isolation between the receivers and group delay is extremely small having no effect on current receiver calibration or operation. Hybrid couplers can also be used to split signals from tower top amplifiers to BTS receivers (remember mismatches on the input side have no effect on the output ports). For in-building distribution systems, hybrids are useful in carrying multiple carrier inputs because the high degree of isolation between the two output ports and the two input ports without unwanted interaction between carriers.
