High-Speed DAC Controls Power Amplifier Ramp Profile

A high-speed current-output DAC and a single op amp can generate a power amplifier (PA) ramp profile that fits the RF gain requirements for TDMA. The ramp is applied to the voltage control pin of a variable-gain amplifier (VGA) to control the gain of the RF signal entering the PA.
