Abstract: An amplifying circuit of a cascade structure prevents damage to an internal element of a transistor due to the high voltage by controlling the current flowing in the transistor according to a magnitude of a supply voltage. A variable resistance part(100) is connected to a power voltage terminal and an output signal terminal. The internal resistance is varied by the control voltage. The current flowing from the power supply voltage to earth is controlled. An amplifier(200) is connected between the variable resistance part and the earth. The input signal is amplified by the amplifier. A capacitor is connected between the output signal terminal and the earth. A resistance variable controller(300) generates a control voltage according to the magnitude of the power supply voltage.

Abstract: A distributive type power amplifier is provided to reduce power loss and to enhance power efficiency by selecting a plurality of power amplification paths having different levels of impedance. A power amplifier unit(100) includes a plurality of power amplifiers(100-1,100-2,100-n). The power amplifiers receive input signals through an input terminal(IN) and amplify the received signals. Each of the power amplifiers is independently turned on or turned off. A matching unit(200) includes a plurality of matching elements(200-1,200-2,200-n). The matching units are connected to an output terminal(OUT) and are connected serially to each other. The matching units have predetermined output impedance. An input matching unit(50) is connected to a signal line between the input terminal and the power amplifier unit.
