Abstract
In one embodiment, an impedance matching network includes an electronically variable reactance element (EVRE) comprising discrete reactance elements and corresponding switches. The switches are configured to switch in and out the discrete reactance elements to alter a total reactance provided by the EVRE. A monitoring circuit is operably coupled to the EVRE. For each discrete reactance element, the monitoring circuit monitors a value related to the discrete reactance element or its corresponding switch. Upon determining the monitored value exceeds a predetermined amount, the monitoring circuit the discrete reactance element of the EVRE from switching in or out.
