Model SWX-40360320-19-4B is a four port, 20 dB U-band full waveguide band crossguide coupler. Unlike most commercial available narrow band couplers, the new crossguide coupler covers full U band waveguide operation.
The crossguide coupler exhibits less than 0.5 dB insertion loss, greater than 20 dB return loss, +/- 1 dB coupling flatness and better than 15 dB directivity over the entire 40 to 60 GHz frequency band. In addition, the crossguide coupler can be made up to 10 dB higher coupling levels.
The crossguide coupler measures 1.3”(W) x 1.3”(L) x 1.2”(T) and weights 2.2 Oz. The full waveguide band crossguide couplers with coupling levels, such as 10, 15, 25, 30 dB from K to W bands, are also available from SAGE Millimeter, Inc.
