Abstract :
A new parallel-strip 90deg hybrid coupler is proposed. By integrating swap into the two-section branch line coupler, the bandwidth is enhanced to be close to that of the four-section coupler. A working prototype designed at 1 GHz is realised and measured. Good agreement between the simulation and measurement is achieved.
