Paper Abstract

A millimeter-wave band coupler at 77.5 GHz with 6 dB couplinglevel has been developed. The coupler offered less than 2.0 dBinsertion loss, ± 0.5 dB variation in coupling level and a typicalisolation of 25 dB over approximately 10 GHz bandwidth. Otherfrequency band couplers with different coupling factor have beendeveloped also. The advantages of this type of directional couplerare its large flexible coupling level selection (from 0 to 100percent), simplicity in design, low cost and excellent producibility.
