Abstract
Aspects of a method and system for matching an integrated FM system to an antenna utilizing on-chip measurement of reflected signals are provided. In this regard a portion of a signal output by an integrated FM radio transmit block and reflected by an antenna may be routed to an on-chip signal analyzer. Accordingly, measurements of the reflected signals may be utilized to configure a matching network in order to provide a best impedance match between the FM radio and the antenna. In this regard, a best impedance match may maximize radiation efficiency and/or radiated power. Additionally, the configuration of the matching network may incorporate a correction algorithm/offset experimentally determined via a calibration utilizing external components.
