Abstract
Systems and methods are disclosed for returning RF components which exhibit a mismatch with a coupled load. A tuning circuit may be coupled to a signal path of the RF component, wherein the tuning circuit includes a plurality of loads, a switching element associated with each load, wherein each switching element brings the associated load into and out of the signal path, a control line for each switching element, and a phase stage configured to introduce a phase shift, such as 90°, between a first subset of the loads and a second subset of the loads. The disclosure also includes routines for establishing optimum settings for the tuning circuit.
