ABSTRACT:
A transmitter of a wireless modem may be ramped up with quicker ramp up times and better splatter control by using software controllable ramp up techniques. A digital data signal source sends data to digital-to-analog converters used to generate a ramp with the desired duration and shape for maximum gain with minimum splatter. A transmitter digital-to-analog converter is sent constant I/Q data to bias the input of the I/Q modulator to maximum gain when combined with a direct current voltage. A controller digital-to-analog converter is sent incremented ramp data to shape the ramp and provide maximum gain at the output of the I/Q modulator.
