An RF(Radio Frequency) modulation module is provided to implement a compact size without a phone jack cable by removing a tuner outputting phone jack. An RF(Radio Frequency) modulation module comprises the followings: a distributor(120) for respectively distributing an RF input signal through an RF input terminal into first and second RF signals; an RF modulator(130) for outputting an RF modulation signal where video/audio signals are modulated; an RF output circuit(140) for outputting the first RF signal from the distributor and the RF modulation signal from the RF modulator; a tuner output pin(TUout) which is formed in a pin type and outputs the second RF signal; a power input pin(DCin) which is formed in a pin type and receives power from the outside; and a power pass circuit(150) for transmitting the power, received through the power in pin, to the RF input terminal.
