Digital pre-distortion compensation
The intermodulation products due to nonlinear distortion are suppressed to -50dB.
The adoption of the digital pre-distortion compensation guarantees the power amplifier unit efficiency of more than 18%.
The output filter is designed to be compact owing to small intermodulation products, and the power supply unit is mounted in each power amplifier unit, realizing the compact 3kW digital broadcasting transmitter.
The equipment incorporates all the necessary functions including the output filter and the dummy load for testing, and the installation work is complete only by connecting the power cable, input signal cable and antenna cable and connecting the equipment to the cooling system.
