PURPOSE: An apparatus for receiving an RF of a mobile phone terminal is provided to additionally insert a blocking RF filter to an existing RF receiving path, so that a developer can develop an RF receiving device of the terminal by easily searching an element for satisfying a single tone desensitization standard. CONSTITUTION: A duplexer(20) transceives an RF with a base station. A blocking RF filter(21) is additionally inserted between the duplexer(20) and an LNA(Low Noise Amplifier)(22), and blocks a transmission power generated via a power amplifier(26) and an isolator(27). The power amplifier(26) and the isolator(27) are included in a transmission device of a terminal. The LNA(22) low noise-amplifies the RF of the duplexer(20). An RF filter(23) filters an RF noise component of the amplified RF. A down mixer(24) mixes the filtered RF with an oscillating frequency, and generates an IF. An IF filter(25) filters a noise component of the generated IF.
