A system and a method for analyzing power of the output stage of a communication module are provided to maximize the transmitting/receiving distance of RF communication devices by deducing the maximum output power value of a power amplifier in accordance with ACPR(Adjacent Channel Power Ratio) and EVM(Error Vector Magnitude) standards and efficiently executing power matching of the power amplifier. A system for analyzing power of the output stage of a communication module consists of a level selection part(110), a power supply part(120), an ACPR value measurement part(130), an ACPR value selection part(140), an EVM value selection part(150), and a value extraction part(160). A user inputs a plurality of PCVs(Power Control Values) for a power amplifier(10) to the level selection part(110). The power supply part(120) supplies power equivalent to each PCV to input stage of the power amplifier(10). The ACPR value measurement part(130) measures ACPR values of the output stage of the power amplifier(10). The ACPR value selection part(140) compares the ACPR values transmitted from the ACPR value measurement part(130) with ACPR spectrum standards and selects the nearest ACPR value to the ACPR spectrum standards. The EVM value selection part(150) creates a PCV list equivalent to the selected ACPR value and obtains a PCV close to the threshold of EVM standards from the PCV list. The value extraction part(160) extracts an output power value corresponding to the obtained PCV.
