PURPOSE: An RF(Radio Frequency) signal processing circuit and an electronic apparatus using the same are provided to prevent the influence resulting from the operating variation of a main tuner unit. CONSTITUTION: A loop-through terminal transfers an RF signal to the outside, and a main tuner unit(400) tunes the RF signal. A first balun circuit(310) transfers the RF signal to the main tuner unit through an RF input terminal or to the loop-through terminal. In order to transfer a signal of the first balun circuit to the loop-through terminal, a second balun circuit(320) is placed between the first Balun circuit and the loop-through terminal. The signal of the first balun circuit is amplified in the RF amplifier(210). The amplified signal is transferred to an adjacent slave tuner unit(500) through the loop-through terminal via the second balun circuit. |
