Abstract: PURPOSE: An amplifier of a triple-band mobile terminal is provided to solve a problem of the increase in the size and a fabrication unit cost of a terminal in case of having two power amplifier in one terminal. CONSTITUTION: Signals of three bands and a control signal for discriminating them are outputted through a main RF processing IC(100). A triple-band integrated power amplifier(200) performs three-stage amplifying of GSM, DCS and WCDMA. At the first and second stages(Amp4,Amp5), TXs of the DCS and WCDMA have the almost same frequencies and low outputs, so the amplifiers(Amp4, Amp5) are commonly used. At the final third stage, the maximum power of the DCS is 30dBm and the maximum power of the WCDMA is 24dBm. Thus, because the power classes and signal modulation methods are different, different amplifiers(Amp6,Amp7) are used. A switch(SW1) is installed inside the power amplifier(200) to switch to the DCS or to the WCDMA according to the control signal outputted from the main RF processing IC(100). A transmission signal which has been outputted from the power amplifier(200) is outputted to an antenna through a switchplexer(300) and operated in TDD, so when a signal is received from the antenna, it is switched to an LNA(Low-Noise Amplifier).
