RF3133 Overview The RF3133 is a quad-band GSM/DCS/PCS power amplifier module that incorporates an indirect closed loop method of power control. This simplifies the phone design by eliminating the need for the complicated control loop design. The indi- rect closed ...

Page 11

Talk time and power management are key concerns in transmitter design since the power amplifier has the highest cur- rent draw in a mobile terminal. Considering only the power amplifier’s efficiency does not provide a true picture for the total ...

RF3133 The switching transients due to low battery conditions are regulated by incorporating the following relationship limiting the maximum V voltage (Equation 4). Although no compensation is required for typical battery conditions, the bat- RAMP tery compensation required for extreme ...

Page 13

Switching transients occur when the up and down ramp of the burst is not smooth enough or suddenly changes shape. If the control slope has an inflection point within the output power range or if the slope ...
