PURPOSE: An RF(Radio Frequency) receiving apparatus for home automation is provided to correctly recognize an RF receiving signal in household appliances by removing signal distortion phenomenon by overlap between an infrared receiving signal and the RF receiving signal. CONSTITUTION: An RF receiving module(10) receives a transmission signal of an RF remote unit, and outputs an RF receiving signal and a control signal which has a low level when generating the RF receiving signal. A control circuit unit(12) blocks an infrared receiving signal and transmits the RF receiving signal to a CPU(54) by the control signal when the RF receiving signal is generated while transmitting an output signal of an infrared receiving module(50) to the CPU(54).
