Abstract

The invention discloses a gallium arsenide-based microwave rectifier chip, which solves the problems of large size and relatively heavy weight of traditional rectifier circuits. The chip is made of 0.25 micron gallium arsenide pHEMT process, and the thickness of the chip is 0.1 mm. The circuit on the chip surface consists of a radio frequency input port (1), a DC blocking capacitor (2), an input matching circuit (3), and a Schottky diode array ( 4), the output filter circuit (5), and the DC output port (6) are sequentially connected to form, and the scribing lane (7) is used for cutting chips. The invention has the advantages of high degree of integration and small size, and can be applied to the fields of wireless energy transmission, electromagnetic energy collection system and the like.

Description

technical field [0001] The invention belongs to the technical field of microwave radio frequency devices, in particular to a rectifier chip in microwave radio frequency devices. Background technique [0002] Wireless energy transmission is an advanced power transmission method, which can transmit electric energy from one end of the space to the other without cables. Electromagnetic energy collection is to receive electromagnetic waves distributed in free space through antennas, and then rectify them into direct current for direct use. Or storage technology is of great significance for improving energy efficiency. Microwave rectifier circuit is the key device of wireless energy transmission and electromagnetic energy harvesting system. It is generally located behind the receiving antenna and converts the radio frequency signal received by the antenna into direct current. The traditional microwave rectifier circuit is to solder nonlinear devices such as diodes and triodes to ...
