Abstract: Techniques for calculating a real power delivered to a transmit load of a transceiver. In an aspect, two distinct voltages are sampled from a matching network coupling the transmit load to an amplifier output. The voltages are coupled by configurable coupling elements to the down-conversion mixers of the transceiver, and are subsequently converted to digital form for processing by a baseband processor. The baseband processor may calculate a coefficient relating the calculated real power to an actual power delivered to the load. The coefficient may be stored and subsequently applied to a transmit element during normal signal transmission by the transceiver. Note the coupling elements may be configured to decouple the sampled voltages from the down-conversion mixers during normal signal reception by the transceiver, thus avoiding unnecessary loading on the receive signal path.

Abstract translation: 用于计算传送到收发器的发射负载的实际功率的技术。 在一个方面，从耦合发射负载到放大器输出的匹配网络对两个不同的电压进行采样。 电压通过可配置的耦合元件耦合到收发器的下变频混频器，并随后被转换为数字形式以供基带处理器处理。 基带处理器可以计算与所计算的实际功率相关联的实际功率与递送到负载的实际功率的系数。 可以在由收发机进行的正常信号传输期间将系数存储并随后应用于发送元件。 注意，耦合元件可以被配置为在收发器的正常信号接收期间将采样的电压与下变频混频器去耦，从而避免在接收信号路径上的不必要的负载。
