Adaptive Impedance Mismatch Detector System
US Patent:
4647871, Mar 3, 1987
Filed:
Nov 22, 1985
Appl. No.:
6/800832
Inventors:
Harvey N. Turner - Raleigh NC
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H03F 152
US Classification:
330298
Abstract:
An adaptive impedance mismatch detector system is provided for determining whether or not a particular load impedance is matched or mismatched to the characteristic impedance of a transmission line. The detector system is capable of determining if a particular load impedance has a value outside of an impedance threshold circle having a center at a location other than at the center of the Smith Chart. 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.
