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 signals or to combine two signals while maintaining high isolation between them.
MECA’s line of high power 3 dB, 90° hybrid couplers covers all wireless band applications from UHF through UMTS (0.400-2.200 GHz) with power levels to 500 watts. Ideal for use as a duplexer for DAS head end systems or combining amplifiers for antenna sharing applications with high isolation. These units are equipped with 7/16 DIN-Female, N-Female or SMA-Female connectors and a rugged aluminum housing coated with a clear iridite finish for long lasting, reliable performance. Made in USA and offer low insertion loss and excellent VSWR. Whether you are designing a duplexer, combining amplifiers or just need a 90° phase shift with high isolation to avoid mixing signals, then MECA’s 705 series will help you achieve your objectives.
