A transmitter RF front-end integrated on a single substrate is enabled to determine whether associated IF amplification stage provides a required transmission gain for transmitting an output signal of an application. A dedicated power amplifier driver within the transmitter RF front-end is configured to provide additional gain, when needed based on the determination, to meet the required transmission gain for transmitting the output signal. The associated IF amplification stage comprises an upconversion mixer and a lowpass filter (LPF). The upconversion mixer may be implemented as an active mixer or a passive mixer. The upconversion mixer and the dedicated power amplifier driver are enabled to operate in 2.44 gigahertz. A maximum gain provided by the associated intermediate frequency (IF) amplification stage for transmitting the output signal is determined to decide the additional gain provided by the dedicated power amplifier driver by comparing with the required transmission gain.
