The power supply is for supplying powers of different levels into a GaAs field effect transistor with preset sequence. The power supply. The power supply includes a first and a second power terminal connected to a first and a second power, a reference terminal connected to a reference power, a first and a second diode connected to the first and the second terminal, a first and a second output terminal connected to the first and the second diode, a first switch controlled by the first terminal to supply the first power to the first output terminal, a second switch connected to the reference terminal to control the first switch according to the second power, and resisters connected to the diodes and the switches.
