Embodiment Construction

[0040] The invention can solve the problems of electromagnetic interference EMI and electromagnetic compatibility EMC through reasonable pin arrangement.

[0041] the following to figure 1 The illustrated embodiments illustrate the technical solution of the invention in detail. See the table below for the specific layout of the pins of the wireless LAN module.

[0042]

[0043]

[0044]

[0045] The following explains the technical significance of each pin arrangement in the above table (the serial number on which the description is based is figure 1 middle pin number).

[0046] Pin 4 and pin 5 are the pins connected to the antenna, so they are set on the same side of the wireless LAN module and can be connected to the antenna nearby, so as to avoid the need for a certain pin to be connected to the antenna with a relatively long wire. In order to avoid mutual influence between pin 4 and pin 5, from figure 1 It can be seen that the distance between the pin 4 and th...

Abstract

In order to solve the problems of electromagnetic interference and electromagnetic compatibility occurring when WLAN chips are integrated into a module, the invention provides a WLAN module for mobile terminals. The problems of electromagnetic interference and electromagnetic compatibility are eliminated or reduced by reasonably sorting pins. The WLAN module can be widely applied to the mobile terminals.

Description

technical field [0001] The invention belongs to the hardware technology of mobile communication and wireless transmission, in particular to a wireless local area network module of a mobile terminal. Background technique [0002] Most of the existing mobile terminal hardware structures are directly connected to the main board of various components, and the wireless local area network (WIFI) chip is also directly arranged on the main board of the mobile terminal. The disadvantage of this setting scheme is that after the wireless LAN chip is connected to the motherboard, an overall test is required. If there is a problem in the test and modification is required, a comprehensive modification of the motherboard is required. When multiple components are installed on the motherboard of the mobile terminal (this is a common situation), repeated testing of multiple modules will lead to a long development cycle and high development costs. [0003] The inventor believes that the wirel...
