PURPOSE: A wide-band broadcasting receiver is provided to prevent the distortion of a signal due to a power difference between high and low frequency bands. CONSTITUTION: A broadband broadcasting receiving apparatus comprises an input amplification unit(100), a variable filter unit(200), a tuner unit(300), and a demodulation unit(400). The input amplifier amplifies the input signal to a preset size through an input terminal. By the selection of an external device, the variable filter unit changes the pass band of the filter. The tuner unit selects a signal including a selected channel among the signal of the variable filter unit. The demodulation unit demodulates the signal of the tuner.
