180° Hybrid Coupler – SMA

Leader microwave’s 180 °hybrids are three and four-port directional couplers designed for a 3 dB power split. They're RF shielded and feature high isolation, a miniature size, low VSWR, low loss, and temperature stability. Hybrid couplers can be used to split signals from tower top amplifiers to BTS receivers, in signal sampler applications to monitor system performance, to inject a signal into a system without interrupting its service, in the creation of reflecting phase shifters, and more. Leader microwave’s 180 °hybrids couplers offer many broadband models covering up to 50 GHz.

LEADER-MW ’s180° hybrids are designed with a double-arrow construction technique in which two stripline, asymmetric, tapered-line directional couplers are cascaded. Meandering transmissionlines on each side of the hybrid maintain the even180-degree phase relationship between channels at all frequencies. Fabrication of the double-arrow hybrids requires asymmetric couplerwith completely overlapped lines at its coupled end (where the lines cross) that form an instantaneous transmission from high coupling to no coupling. The hybrids are constructed with a three-layer stripline configuration. Coupled lines are etched on opposite sides of a thin coupler circuit board, sandwiched between a pair of equal-thickness dielectric boards.
