TIDA-00897, High-Accuracy Logarithmic RMS Power Detector Reference Design for WLAN Applications

TIDA-00897, High-Accuracy Logarithmic RMS Power Detector Reference Design for WLAN Applications. Dynamic transmit-power control is critical for improving spectral efficiency and reducing adjacent channel interference in wireless local area networks (WLANs). In addition, regulatory agencies worldwide require that transmit power be limited to certain level to reduce interference with other communication equipment. Another benefit of transmit power control in WLAN systems is to prolong battery life by reducing power-supply voltage to the power amplifier. This design provides a solution for closed-loop dynamic transmit power control for WLAN application
