摘要： Methods and systems for WCDMA power amplifier closed loop power control are disclosed and may include determining a magnitude of an output RF signal generated by a power amplifier (PA), and configuring a gain of a PGA coupled to an input of the PA via closed-loop feedback to maintain a desired magnitude of the output RF signal. The closed-loop feedback architecture may include a slot-based and/or a real time-based control. A signal proportional to the output signal may be generated by an envelope detector. The signal generated by the envelope detector may be utilized to generate a root-mean-squared (RMS) value. The gain of the PGA may be configured by comparing the RMS value to a desired magnitude of the output signal over a time slot and/or utilizing a real time error signal generated by subtracting the signal proportional to the magnitude of the output signal from a desired magnitude.

摘要： Wideband-Code Division Multiple Access (W-CDMA) transmit architecture. A baseband digital processing module operates cooperatively with an analog signal processing module to effectuate highly adjustable and highly accurate gain adjustment in accordance with transmitter processing within a communication device. The gain adjustment and/or gain control is partitioned between the digital and analog domains by employing two cooperatively operating digital and analog modules, respectively. Gain adjustment in the analog domain is performed in a relatively more coarse fashion that in the digital domain. If desired, gain adjustment in each of the analog and digital domains is performed across a range of discrete steps. The discrete steps in the analog domain are larger than the discrete steps in the digital domain. Also, the discrete steps in the digital domain may be interposed between two successive discrete steps in the analog domain.

摘要： Enhanced polar modulator for transmitter. Within a phase locked loop (PLL), a two point modulation topology is employed in which phase information passes through a limiter (e.g., a +90° or +re/2) in which the phase information dynamic range is divide by a factor (e.g., by 2) and a maximum frequency deviation is also divided by a factor (e.g., by 2). Then, a double balanced up-converter mixer/modulator is implemented to perform gain adjustment (e.g., magnitude and/or amplitude adjustment) and phase changes of 0° and +180° or 0 and +re (e.g., negative gains values may be employed). Phase adjustment in such an architecture is split and provided to both the PLL and to the mixer/modulator of such a polar modulator within a transmitter module such as may be implemented within a communication device (e.g., which may be a wireless communication device). This architecture that includes a PLL with a double balanced up-converter mixer/modulator suppresses even harmonics.
