Abstract

The present application relates to a radio frequency system, an antenna switching method, and a customer front-end device. The radio frequency system includes a receiving module for receiving and processing radio frequency signals; each antenna of M antennas is connected to the receiving module with a radio frequency transceiver, which is configured with M radio frequency transceivers. The M antennas are connected to the M ports through the receiving module in a one-to-one correspondence to form a preset receiving and transmission path of each antenna; wherein, the radio frequency transceiver stores the configuration information of the preset receiving and transmission path, and is also used for according to each The RF signal received by the port determines the target transceiver antenna group. The target transceiver antenna group includes N antennas, where 2≤N<M; it can reduce the insertion loss of the RF front-end circuit in the RF system, improve the sensitivity performance, and further improve the RF system communication performance.

Description

technical field [0001] The present application relates to the field of antenna technology, and in particular, to a radio frequency system, an antenna switching method, and a customer pre-installation device. Background technique [0002] Customer Premise Equipment (CPE) is a mobile signal access device used to receive mobile signals and forward them with wireless WIFI signals. It is also a kind of high-speed signal, such as 4G or 5G signal, into WiFi signal. equipment. Generally, multiple antennas are configured in the customer premises equipment to support receiving switching of multiple antennas. However, in order to realize the multi-antenna switching technology, it is necessary to add a multi-level switch in the radio frequency system, and its control logic is complicated, and also affects the communication performance of the radio frequency system. SUMMARY OF THE INVENTION [0003] The embodiments of the present application provide a radio frequency system, an anten...
