Abstract

The embodiment of the invention provides a base station radio frequency device. The device comprises a transceiver; a sending amplifier; a receiving amplifier; an antenna unit configured to send first signals of a first frequency range and receive second signals of a second frequency range, wherein the first frequency range and the second frequency range are two different unlicensed frequency ranges; an isolation module configured to isolate the first signals from the second signals, wherein the sending amplifier is connected with the transceiver and the isolation module, the receiving amplifier is connected with the transceiver and the isolation module, and the isolation module is connected with the antenna unit. According to the embodiment of the invention can reduce the design complexity of the radio frequency device of the base station and realizes LTE-U technology in the condition of reducing the design cost and the production cost.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a base station radio frequency device. Background technique [0002] With the rapid development of mobile smart devices, the sharp increase in the number of wireless users, and the rapid emergence of high-definition multimedia streaming services, the contradiction between the growing wireless demand and the expensive and limited licensed spectrum has become increasingly prominent. In order to alleviate the licensed mobile network Due to the pressure of the environment, the method of deploying Long Term Evolution (LTE, Long Term Evolution) by utilizing relatively abundant unlicensed frequency bands has emerged. [0003] The license-free frequency bands are mainly concentrated around the 2.4 gigahertz (GHz) and 5GHz frequency bands, while the vicinity of 2.4GHz is occupied by access technologies such as WiFi, Wireless Fidelity and Bluetooth, and the vicinity of the 5GHz frequ...
