FRONT-END CIRCUIT OF MULTI-BROADCASTING RECEIVER

摘要

A front end circuit of a multi-broadcast receiver is provided to improve performance and reliability by preventing distortion of a reception signal in a strong field. A filter(110) selects an RF broadcast signal among reception signals. A dividing unit(120) divides the RF broadcast signal from the filter(110) into the first and second broadcast signals(RF1,RF2). A level attenuating unit(130) attenuates the first broadcast signal from the dividing unit(120) to a pre-set level. An LNA(Low Noise Amplifier)(140) amplifies the first broadcast signal from the level attenuating unit(130) to have a low noise. A peaking capacitor circuit(150) compensates a high frequency component of the second broadcast signal from the dividing unit(120) and outputs the same via a loop through output terminal(OUT-LT).
