BROADCAST RECEIVER HAVING ENLARGED DYNAMIC RANGE

摘要

A broadcasting receiver having enlarged dynamic range is provided to enlarge a dynamic range of an input RF signal by distributing and amplifying an input RF signal, thereby effectively receiving an analog broadcasting signal and a digital broadcasting signal and providing good quality images. A broadcasting receiver having enlarged dynamic range includes a distributing unit(110), an amplifying unit(120), a tuner unit(140), and a jointing unit(130). The distributing unit distributes a plurality of RF(Radio Frequency) signals with a particular power level of an input RF signal. The amplifying unit amplifies the RF signal received from the distributing unit to a predetermined size. The jointing unit joints the RF signal received from the amplifying unit to one RF signal. The turner unit converts the RF signal received from the jointing unit into an IF(Intermediate Frequency) signal.
