An apparatus for digitally controlling the launch of high-power broad-band RF waves with high linearity for use with a software defined air-interface system. A wave launcher contains an Eplane array containing a plurality of Epixel partition elements is configured with a master digital controller. The master digital controller processes all signals to be launched as RF waves and develops the digital images necessary for digital synthesizers to format the signals to be converted to analog. A plurality of digital-analog converters coupled with power amplifiers convert the digital signal to analog, and the analog signal is then sent to the partition elements to be transmitted as RF waves.
