A radio frequency filter includes a first conductive pattern; a second conductive pattern connected to a first point of the first conductive pattern and extended; a third conductive pattern connected to a second point of the first conductive pattern and extended to surround a portion of the second conductive pattern; a fourth conductive pattern; a fifth conductive pattern connected to a third point of the fourth conductive pattern and extended; and a sixth conductive pattern connected to a fourth point of the fourth conductive pattern and extended to surround a portion of the fifth conductive pattern. The first conductive pattern extends toward the fourth conductive pattern and the fourth conductive pattern extends toward the first conductive pattern. A distance between the first conductive pattern and the fourth conductive pattern is greater than or equal to a distance between the third conductive pattern and the sixth conductive pattern.

A channel searching method may include setting a first channel in a broadcast signal, determining signal strength of the broadcast signal and generating an automatic gain control signal for the first channel, and when the signal strength satisfies a preset first requirement and the automatic gain control signal satisfies a preset second requirement, skipping demodulation of the first channel.
