Double-Ridge Dual Loop Couplers

Double-Ridge Dual Loop Couplers

SMC has an extensive line of double-ridge waveguide Dual Loop Couplers. Coupling values range from -30 dB to -60 dB with optimal coupling flatness. Operational bandwidth is typically 30% 0f the band. Directivity ranges from 15db to 25dB, depending on the selected bandwidth.


Double-Ridge Waveguide Dual Loop Couplers

Different male or female coaxial connectors are available Upon Request (TNC, SC, K, N, 2.4 mm, 2.92, 3.5 mm, 1.85 mm).
Pressurized and TVAC units are available based on the client requirement.
Couplers can be provided with 30,40,50,60 dB coupling.
Directivity and Coupling sensitivity can be enhanced for partial band operation.
*WRD250S/WRD600 are SMC special designed double-ridge waveguide structures that cover extremely wide band 3:1.
*WRD600P is an SMC special designed double-ridge waveguide structure with exceptional high power handling capability.
