AMPLIFIER MODULE IN THE TDD FOR ACQUISITION OF SYNCHRONIZATION USING RF POWER AND THE METHOD THEREOF

摘要

An amplifier module in a TDD(Time Division Duplex) for acquisition of synchronization using RF(Radio Frequency) power and a method for acquiring synchronization by using the same are provided to remove a complicated structure for demodulation by accurately switching the up link and down link by acquiring the synchronization through detection of PF power. An amplifier module(100) in a TDD for an acquisition using an RF power includes an amplifying unit(110), an RF power detecting unit(120), and a power supply unit(130). The amplifying unit(110) amplifies an inputted signal with high power and outputs the amplified signal. The RF power detecting unit(120) continuously detects the RF power inputted to the amplifying unit(110) at predetermined time intervals and provides the RF power to a control unit(140). The power supply unit(130) controls a bias of the amplifying unit(110) according to a control signal inputted from the control unit(140).
