Circuit Description - TX Function The device implements Skyworks Polar Loop transmit architecture. This architecture autonomously splits the amplitude and phase within the device using the traditional analog In-Phase and Quadrature (I/Q) signals. The filter-saving advantage of the translation-loop approach is embedded in the architecture. Also included is an AM loop that provides both signal AM and power level control. The transmitter is provided a coupled feedback signal from the PA and downcon
