主权项

1. An apparatus comprising:
a first power amplifier having a first output for providing a first signal; a second power amplifier having a second output for providing a second signal; and a quadrature lattice matching network including a first path coupled with the first output of the first power amplifier and having a series inductor and a shunt inductor that substantially provide a positive forty-five degree phase shift to the first signal, and a second path coupled with the second output of the second power amplifier and having a series capacitor and a shunt capacitor that substantially provide a negative forty-five degree phase shift to the second signal, wherein the first power amplifier is configured to operate with a phase difference of approximately ninety degrees with respect to the second power amplifier.
