Abstract

PURPOSE: A device for transceiving signals of a remote controller is provided to convert infrared rays signals of the remote controller into high-frequency signals, and to re-convert the high-frequency signals into infrared signals so as to control a corresponding electric equipment. CONSTITUTION: Infrared rays(IR) signals of a remote controller are detected in an optical diode of an IR/radio frequency(RF) converter. The IR signals are converted into electric signals. A mixer mixes output signals of an input amplifier with oscillating frequencies of an oscillator, to modulate the oscillating frequencies according to the output signals of the input amplifier. The modulated signals are amplified to a transmission level in an RF amplifier, and transmitted through a transmitting antenna. RF signals received in a receiving antenna of an RF/intermediate frequency(IF) converter(30) are low-noise amplified in a low noise amplifier(32), and supplied to a mixer(35) through an RF band pass filter(33). The mixer(35) mixes RF signals through the RF band pass filter(33) with oscillating frequencies of an oscillator(34), to supply IF signals. The IF signals are restored to original data through an IF band pass filter(36). A voltage value of restored analog data in a frequency modulation(FM) detector(37) is compared with a preset reference voltage in a comparator(38). The analog data of the FM detector(37) are converted into digital data.
