Abstract

The invention provides a radio frequency system enhancing 2G / 3G sensitivity. The system comprises a radio frequency transceiver main module which is used for transmitting and receiving radio frequency signals, a main receiving module which is used for sending signals received by a main antenna to the radio frequency transceiver main module, and a diversity receiving module which is used for sending signals received by a diversity antenna to the radio frequency transceiver main module, wherein the main receiving module is connected with the radio frequency transceiver main module, and the diversity receiving module is also connected with the radio frequency transceiver main module. By switching a main antenna mode to a main and diversity antenna multiplex mode, an RX path is switched from a single channel to double channels, and the 2G / 3G signal receiving sensitivity is enhanced.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a radio frequency system for enhancing 2G / 3G sensitivity. Background technique [0002] With the rapid development of science and technology, in the field of mobile communication, 2G (2nd Generation, second-generation mobile communication technology) and 3G (3rd Generation third-generation mobile communication technology) are mature and widely used technologies, based on GSM ( The 2G of Golbal System for Mobile Communication (Global Mobile Communication Technology) and the 3G network represented by WCDMA (Wideband code division multiple access) have been deployed and applied on a large scale around the world. [0003] At present, mobile phones have fully entered the 4G era. So far, the communication network has spanned three modes of 2G / 3G / 4G. However, due to the different demodulation methods of these communication network modes, the radio frequency devices used a...
