Tunable and Integrated Impedance Matching and Filter Circuit

摘要

A high performance integrated tunable impedance matching network with coupled merged inductors. Embodiments include a combination of merged multiport constructively coupled spiral inductors and tunable capacitors configured to reduce insertion losses, circuit size, and optimization time while maintaining a high Q factor for the coupled spiral inductors. Some embodiments integrate one or more filter circuits with a tunable impedance matching network, useful in conjunction with such applications as radio frequency power amplifiers.

1. A tunable impedance matching and filtering circuit including:
(a) a coupled merged inductor having at least three ports, at least one such port configured to receive an input signal and at least one other such port configured to output a filtered impedance matched output signal; (b) a plurality of tuning circuits, each electrically connected to a corresponding one of the at least three ports of the coupled merged inductor; and (c) at least one filter circuit, each electrically connected to one or more of the at least three ports of the coupled merged inductor.
