Digital Broadcasting

Terrestrial broadcasting, with its wide coverage and efficient transmission capabilities, remains one of the most popular forms of communication in many countries around the world. In this era of rapid digital development, traditional wireless television and radio continue to be the most widely accessible communication channels, despite the availability of diverse information dissemination methods. These traditional media are regarded as the most direct and reliable way to connect with audiences.

In these broadcasting systems, digital television transmission technology has become the standard. A typical digital television system consists of a transmission setup with two core components: the exciter and the RF power amplifier (RFPA). The exciter's function is to receive the baseband signal and process it so that it can modulate a radio frequency carrier. The modulated signal is then amplified by the RF power amplifier to ensure sufficient signal strength, allowing it to cover longer distances during transmission and maintain signal quality. Through this process, television and radio content can be delivered clearly and effectively to audiences in remote areas.
