Abstract :
W-band broadband couplers having 6-, 10-, and 3-dB coupling ratios realized by coupled finline are reported. For looser coupling, such as 6- and 10-dB coupling, an overcoupling configuration is used in order to decrease the finline dimensions. The experimental results for prototype couplers show a flat frequency response and low-loss performance over a broad band.<>
