Broadwall Directional Coupler Series: 141

UBS offers a standard product line of multi-hole coax broadwall directional couplers covering waveguide sizes from WR-28 through WR-284. The optimum electrical characteristics of high directivity and coupling flatness are achieved utilizing a precision machined Tchebyscheff coupling hole distribution and a precision ground tapered load element in the secondary arm.
