<p>An adaptive impedance mismatch detector system (10) for determining whether or not a particular load impedance (30) is matched or mismatched to the characteristic impedance of a transmission line (at 20). The detector system is capable of determining if a particular load impedance has a value outside of an impedance threshold circle (24) having a center (22) at a location other than at the center of the Smith Chart (Fig. 2). The system changes the radius and/or center of the threshold circle in response to changes in circuit operating conditions or parameters. This flexibility enables the detector to be more selective in determining improper load conditions.</p> |
