A method (800) and an apparatus for controlling transmission power
associated with a transmitting unit (220) are described herein. The
transmitting unit (220) generally includes a processing component (310),
a baseband controller (320), a linearization controller (330), a variable
baseband source (340), and a radio frequency (RF) component (350). The
variable baseband source (340) may generate a baseband signal based on an
input signal. The RF component (350) may generate an RF signal based on
the baseband signal. The processing component (310) may generate a first
control signal and a second control signal. Further, the processing
component (310) may provide the first control signal to the baseband
controller (320) to adjust the variable baseband source (340), and
provide the second control signal to the linearization controller (330)
to adjust the RF frequency component (350).
