    • 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.
    • 提供了利用片上测量反射信号来将集成系统与天线进行匹配的方法和系统的方面。 在包括接收器的至少一部分和发射器的至少一部分的芯片中,可以基于从天线反射的一个或多个信号的片上测量来确定天线和芯片之间的最佳阻抗匹配。 可以使用校正算法来确定天线和芯片之间的最佳阻抗匹配。 校正算法可以利用来自测量由芯片经由天线发射的信号的外部测试装置的数据来确定。 反射信号可以通过片上定向耦合器被路由到信号分析器。 可针对多个频率和/或多个发射信号强度中的每一个确定最佳阻抗匹配。

    • Methods and systems for optimizing an FM transmitter and FM receiver in a single chip FM transmitter and receiver are disclosed and may include receiving an FM signal from each of multiple selected antenna configurations. The received signal strength obtained for each configuration may be measured and stored in a memory, and FM signals may be transmitted and/or received utilizing a configuration that generates a received signal strength above a desired threshold from the measurement. The FM transmitter and receiver may be integrated on-chip, and may be impedance matched to the antennas utilizing selectable capacitors integrated on-chip and/or off-chip and selectable inductors located off-chip. The multiple antennas may comprise antennas that are internal and antennas that are external to the wireless device, each of which may be tuned for one or more wireless protocols. One or more of the antennas may comprise metal components within the wireless device.
