摘要：
A directional coupler with increased directivity and reduced overall footprint area is disclosed. There is an input port, an output port, a coupled port, and a ballasting port. A primary chain of serially connected inductors is connected to the input port and the output port, while a secondary chain of serially connected inductors is connected to the coupled port and the ballasting port. A first compensation capacitor is connected to the input port and the coupled port, and a second compensation capacitor is connected to the input port and the ballasting port.
