Abstract

An amplifying apparatus for a mobile station receiver is disclosed. A low-noise amplifier amplifies a received signal to a preset level. A controller detects a level of a signal corresponding to a first frame of the received signal output from the low-noise amplifier, and generates a control voltage according to the detected level. An attenuation determining resistor determines an attenuation of the received signal. A first switching element is connected in series to the attenuation determining resistor, and is turned ON according to the control voltage so as to attenuate the received signal through the attenuation determining resistor. An impedance compensation resistor is connected in parallel to the attenuation determining resistor, and compensates for a decrease in an impedance due to turn-ON of the first switching element. Further, a second switching element is connected in parallel to the impedance compensation resistor and the first switching element. The second switching element is turned ON according to the control voltage so as to provide the received signal to the low-noise amplifier without attenuation.
