Telephone functional module for mobile terminal

Abstract

The invention provides a mobile phone functional module of a mobile terminal, which aims to solve the problems of electromagnetic interference and electromagnetic compatibility when a chip with a mobile phone function is integrated into a module. The electromagnetic interference among signals of pins is reduced or eliminated by reasonably arranging the pins. The mobile phone functional module canbe widely applied to mobile communication terminals.

Description

technical field [0001] The invention relates to a mobile communication technology, in particular to a telephone technology in the mobile communication. Background technique [0002] Most of the hardware architectures of existing mobile terminals are that each component is directly welded on the main board, and the chip that realizes the telephone function is also directly welded on the main board of the mobile terminal. The disadvantage of this setting scheme is that after soldering the chip that realizes the phone function to the main board, an overall test is required. If there is a problem in the test, then targeted modification is required. When there are only one functional module (this is a common situation), repeated testing of multiple modules will lead to a long development cycle and high development costs. [0003] The chip that realizes the phone function and related circuits are integrated into a module that can be soldered to the main board of the mobile termin...
