    摘要: A radio frequency (RF) front-end circuit and an operating method thereof are provided. The proposed RF front-end circuit includes a first linear amplifier, a second linear amplifier, and a calibration unit. The first linear amplifier performs a high-frequency amplification on a RF signal to generate an amplified RF signal, and down-converts the amplified RF signal into an intermediate frequency (IF) signal. The second first linear amplifier performs a low-frequency amplification on the IF signal to generate an amplified IF signal. The calibration unit is coupled to the first and the second linear amplifiers, and receives a voltage gain fed back from the second linear amplifier. Then, the calibration unit performs an auto-calibration procedure according to the voltage gain fed back from the second linear amplifier to search for an input current value of the first linear amplifier, which correspondingly maximizes the voltage gain of the first amplifier.
