Radio frequency circuit debugging method

Abstract

The invention provides a radio frequency circuit debugging method. The radio frequency circuit debugging method comprises the following steps: forming a light drawing file according to a radio frequency circuit design scheme; establishing a model in simulation software through the light drawing file, and setting information of each layer and port information of the model; applying an electronic device model needing to be matched to a simulation model to form multiple matching circuit models; simulating each matching circuit model, changing the parameters of the electronic device to achieve impedance matching, and acquiring matching parameters of the matching circuit models; and using a matching circuit having the matching parameter as the matching circuit of an actual radio frequency circuit. By adopting the radio frequency circuit debugging method, the debugging efficiency can be improved.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to a radio frequency circuit debugging. Background technique [0002] Due to the popularity of the Long-Term Evolution (LTE) standard, there will be many frequency bands on a smart phone to support all operators, especially for all Netcom models, with as many as 13 or even more frequency bands. The debugging work of RF engineers has brought great pressure. At present, the existing technology needs to use a vector network analyzer to debug each frequency band separately after the mobile phone patch is returned, which is time-consuming and laborious. [0003] Please see figure 1 , is a schematic flowchart of debugging a radio frequency circuit in the prior art. [0004] Step S101: drawing a schematic diagram of a mobile phone, and drawing a printed circuit board (PCB). [0005] Step S102: Generating a light painting file. [0006] Step S103: The manufacturer produces prin...

Problems solved by technology

[0011] On average, it takes more than 4 hours to complete the commissioning of a frequency band. The workload of engineers is huge and time-consuming, which affects the progress of the project and the cost of the company is high.

Moreover, during the debugging process, multiple replacements of devices can easily damage the mobile phone board, resulting in a decline in yield

R & D personnel have long-term exposure to the welding environment, which is not good for their health
