... Dual-Band GSM Handsets • Commercial and Consumer Systems • Portable Battery-Powered Equipment Product Description The RF3110 is a high-power, high-efficiency power ampli- fier module with integrated power control. The device is self-contained with 50 input and output terminals. The power control function is also incorporated, eliminating the need for directional couplers, detector diodes, power control ASICs and other power control circuitry ...

... Equation 1 where the relationship between collector voltage and output power is shown. Although load impedance affects out- put power, supply fluctuations are the dominate mode of power variations. With the RF3110 regulating collec- tor voltage, the dominant mode of power fluctuations is eliminated – ...

... VCO. The RF3110 presents a very constant load to the VCO. This is because all stages of the RF3110 are run at to prevent the RAMP constant bias result, there is constant reactance at the base emitter and base collector junction of the input stage to the power amplifier ...

... VCO decreases (or increases) with respect to temperature or supply voltage. The burst timing then appears to shift to the right especially at low power lev- els. The RF3110 is insensitive to a change in input power and the burst timing is constant and requires no software compensation. Switching transients occur when the up and down ramp of the burst is not smooth enough or suddenly changes shape ...
