Abstract
A zero insertion loss directional coupler includes an input port, an antenna port, an isolation port, and a detect port. The coupler has a first signal trace, a second signal trace, and an inductive winding. The first signal trace is on one of two layers and is connected to the input port and the antenna port, while the inductive winding is on another one of the two layers. A first terminal of the inductive winding is connected to the isolation port. A first terminal of the second signal trace is connected to the detect port and a second terminal of the second signal trace is connected to a second terminal of the inductive winding.
