Abstract
Aspects of a method and system for matching an integrated system to an antenna utilizing on-chip measurement of reflected signals are provided. In a chip comprising at least a portion of a receiver and at least a portion of a transmitter, a best impedance match between an antenna and the chip may be determined based on on-chip measurement of one or more signals reflected from the antenna. The best impedance match between the antenna and the chip may be determined utilizing a correction algorithm. The correction algorithm may be determined utilizing data from an external test set that measures signals transmitted by the chip via the antenna. The reflected signals may be routed to a signal analyzer via on on-chip directional coupler. The best impedance match may be determined for each of a plurality of frequencies and/or each of a plurality of transmit signal strengths.
