ABSTRACT:
An RF transmitting apparatus is used for converting audio signals output from a sound card of a computer to RF signals and transmitting the RF signals. The RF transmitting apparatus comprises an interface, a modulating module, an amplifying module, a transmitting module, and an antenna. The interface is coupled to the sound card for receiving the audio signals, and rearranging the audio signals to be data packages. The modulating module is coupled to the interface for generating a carrier wave and receiving the data packages, and modulating the carrier wave with the data packages to generate modulated signals. The amplifying module is coupled to the modulating module for amplifying the modulated signals. The transmitting module is coupled to the amplifying module for converting the modulated signals to the RF signals. The antenna is coupled to the transmitting module for transmitting the RF signals.
