| Abstract: | A design of coaxial directional coupler is described for use in laboratory calibration work in which directivity better than 40 dB and v.s.w.r. better than 1.02 are necessary over wide frequency ranges. The coupling factor varies with frequency in a regular manner, but this is not a serious disadvantage. |
