Abstract
A quadrature coupler includes four ports, four inductors, and six capacitors. The first through third capacitors are coupled in series between the first and fourth ports. A first intermediate node is between the first and second capacitors. A second intermediate node is between the second and third capacitors. The fourth through sixth capacitors are coupled in series between the second and third ports. A third intermediate node is between the fourth and fifth capacitors, and a fourth intermediate node is between the fifth and sixth capacitors. The first inductor is coupled between the first and second ports. The second inductor is coupled between the first and third intermediate nodes. The third inductor is coupled between the second and fourth intermediate nodes. The fourth inductor is coupled between the fourth and third ports. Variable tuning networks may be coupled between the first and fourth ports and the second and third ports.
