Abstract

The invention discloses a wireless communication module which comprises a baseband chip, an antenna, a single-pole double-throw switch, a signal transmission branch and a signal receiving branch. The signal receiving branch comprises a band-pass filter, a single-pole three-throw switch, a low noise amplifier and an attenuator, the band-pass filter is connected with the antenna through the single-pole double-throw switch, the single-pole three-throw switch is connected with the band-pass filter, and the three branches of the single-pole three-throw switch are respectively connected to the baseband chip directly and through the low noise amplifier and the attenuator. The wireless communication module selects the corresponding signal transmission route according to the intensity of the signals received by the antenna and conducts amplification, attenuation or shoot-through on the signals, and therefore the signal receiving range of the wireless communication module is expanded.

Description

technical field [0001] The invention relates to wireless communication equipment, in particular to a wireless communication module for expanding the range of signal receiving. Background technique [0002] As users have higher and higher requirements for wireless network data throughput, wireless network standards can support higher network throughput to meet user needs, but when the network throughput is higher, the strength of the transmission signal is required to be higher and higher. Small. When a user uses a home wireless network to transmit data between electronic devices, due to the relatively strong transmission signal, the wireless network standard that supports high throughput cannot be used in the home environment, so high-speed data transmission cannot be achieved, which greatly affects wireless products. performance when used in a home environment. Contents of the invention [0003] In view of this, the present invention provides a wireless communication mo...
