High Performance Integrated Tunable Impedance Matching Network with Coupled Merged Inductors

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.

1. A tunable impedance matching network including:
(a) a coupled merged inductor having an input port and at least two output ports; (b) a first tunable capacitor electrically connected in a shunt configuration from a first one of the at least two output ports of the coupled merged inductor to circuit ground; and (c) a second tunable capacitor electrically connected in a shunt configuration from a second one of the at least two output ports of the coupled merged inductor to circuit ground.
