... The indirect closed loop is essentially a closed loop method of power control that is invisible to the user. Most power con- trol systems in GSM sense either forward power or collector/drain current. The RF3133 does not use a power detector. A high-speed control loop is incorporated to regulate the collector voltages of the amplifier while the stages are held at a constant bias ...

... BAT Where P is the output power from the PA ered DC power. The RF3133 improves the effective efficiency by minimizing the P introduce 0.4dB to 0.5dB loss to the transit path. To demonstrate the improvement in effective efficiency consider the fol- lowing example: Conventional PA Solution: RF3133 Solution: The RF3133 solution improves effective efficiency 5%. ...
