Tuner for compensating for take-over point depending on temperature

Abstract

The present invention relates to temperature compensation of a tuner, and more particularly, to a tuner in which Take-Over Point (TOP) is compensated for according to a temperature. The tuner according to the present invention down-converts a Radio Frequency (RF) wireless signal and outputs the converted signal. The tuner compensates for a TOP depending on a temperature and includes: received signal strength detection means for detecting a received signal strength depending on a RF output of the tuner and transmitting the detected strength to a gain control unit; temperature measurement means for measuring an operating temperature of the tuner and transmitting the measured temperature value; a compensation unit for receiving the measured temperature value from the temperature measurement means to compare the received temperature value with a reference TOP value, compensating for the TOP value depending on variation in temperature and outputting the compensated value; and a gain control unit for receiving the compensated value from the compensation unit to controls the RF output based on the TOP value and the received signal strength received from the received signal strength detection means.
