Summary

The RF3196 is the next generation of PowerStar® Power Amplifiers. The type of power control used in the RF3196 is a closed

loop method that regulates the collector voltage of the amplifier while the stages are held at a constant bias. The VBATT track-

ing circuit monitors VBATT levels so that the transient spectrum never degrades and the new power flattening circuit reduces

power and current variation in high current situations.
