Abstract

The invention is applicable to the technical field of power devices. The invention provides a power device preparation method. According to the method, the pre-distortion circuit and the impedance converter are integrated to form a monolithic microwave integrated circuit; a high-linearity power device is realized in combination with a matching design in a power chip; the problems that a power device designed through a conventional method is insufficient in linearity and difficult to miniaturize during high-power and high-efficiency application are effectively solved, the linearity of the powerdevice is remarkably improved, the circuit size is greatly reduced, and the size and the weight of assembly products such as a solid-state power amplifier of a communication electronic system can beeffectively reduced.

Description

technical field [0001] The invention belongs to the technical field of power device design, and in particular relates to a method for preparing a power device. Background technique [0002] With the rapid development of modern communication technology, the wireless communication standard has increased the signal bandwidth, and put forward higher linearity requirements for the power device that plays the role of power amplification in the transmitter of the communication electronic system. Larger baseband signals, communication electronic systems, especially power devices in transmitters, need to meet the requirements of high power, high linearity, high efficiency and miniaturization at the same time. [0003] For power devices, the conventional methods to achieve high power, high linearity, high efficiency and a single performance in miniaturization are generally mutually restrictive or even contradictory, and it is difficult to achieve high power, high linearity and high ef...
