Title :
A New Class of Microstrip Directional Couplers
Abstract :
By using Cohn´s slotline in combination with a microstrip, simple 90° as well as 180° directional couplers of any coupling value can be made. As examples an ultra flat 10 db coupler for 1 - 12 GHz, an octave wide (2 - 4 GHz) magic tee and an almost lumped proximity coupler for 2 - 8 GHz (all on alumina substrate) have been made.
