Problems solved by technology

[0006] Since the coupler is used as a discrete device in the microwave / RF PCB and is connected to the microwave / RF PCB by soldering, the application of the coupler in the microwave / RF PCB increases the purchase cost and assembly cost of the PCB, occupying The area and weight of the PCB, and the solder joints of the discrete coupler on the microwave / RF PCB reduce the reliability of the PCB to a certain extent. Therefore, it is impossible to fully utilize the targeted design of the coupler to maximize the circuit performance

Abstract

This invention provides a realization method for designing a coupler in a PCB aiming at designing the coupler, especially the wide edge coupler in a PCB, which reduces the electro-magnetic radiation to outside or magnet sensitivity from outside so as to improve the magnet compatibility. The purchase and assembly cost are reduced since the coupler is designed in PCB and influence of weld points to the PCB is avoided..

Description

technical field [0001] The invention relates to a printed circuit board, in particular to a realization method for integrating a coupler into a printed circuit board. Background technique [0002] The coupler device is a purely microwave passive device. The principle of the coupler device was published in relevant microwave magazines as early as the 1850s. However, due to the difficulty in the simulation design of the coupler device, the need for ultra-thin dielectrics with appropriate thickness accuracy, and high processing accuracy requirements, until recent years It was mass-produced and applied in the form of discrete devices in the last year. [0003] At present, couplers have been widely used in microwave transceiver channels. Since the application of couplers has nothing to do with the standards, they can be applied to many wireless access standards such as GSM (Global System for Mobile Communications), GPRS (General Packet Radio Service), WCDMA (Wideband Code Divis...
