METHOD FOR CLOSED-LOOP TUNER IN A RECEIVER ANTENNA |
| 摘要 |
Described herein are architectures, platforms and methods for implementing a closed-loop tuner in a receiver circuitry of a portable device. For example, the closed-loop tuner is based upon a configured or an inherent local oscillator (LO) leakage power in the receiver circuitry of the portable device. |

1. A method of tuning in a receiver portable device comprising:
measuring a local oscillator (LO) leakage power produced by at least one LO in the receiver portable device; measuring an antenna impedance based upon the measured LO leakage power; determining an antenna tuning based upon the measured antenna impedance; and tuning the antenna in response to detecting an out-of-tune antenna. |
