Courtesy of Marki Mircowave : CBR17-0026 High Directivity Bridge Coupler
The CBR17-0026 offers the broadest bandwidth of any standalone bridge coupler on the market. It provides an extremely high degree of measurement accuracy for forward power measurements, and can also be used to measure VSWR/return loss (see Directivity and VSWR Measurement App Note). The flat coupling ratio, high directivity, and broadband performance from 200 kHz to 26 GHz make the CBR17-0026 an excellent ‘black box’ coupler for everyday lab use.
