The present application discloses a method and device for real-time switching of radio frequency channels on a time division duplex LTE baseband board. The method includes: receiving a switching request signal for switching a radio frequency channel on a time division duplex LTE baseband board; outputting a control signal for controlling the switching of the radio frequency channel on the time division duplex LTE baseband board according to the switching request signal; processing the control signal, Complete the handover request of the radio frequency channel on the time division duplex LTE baseband board. By processing the control signal, real-time switching of the radio frequency channel on the time division duplex LTE baseband board can be realized.
Description
technical field [0001] The present application relates to the technical field of radio frequency channel switching, and in particular, to a method and device for real-time switching of radio frequency channels on a time division duplex LTE baseband board. Background technique [0002] According to 4-channel TDD-LTE products and customer needs, to achieve free switching of single-board multi-frequency bands, all RF channels must be collected on one antenna during operation, only one channel is working at the same time point, and the other RF channels must be Off, all switching should be completed within 100nS. [0003] In the process of realizing the prior art, the inventors found that: [0004] The prior art is completed by logic circuits, but the disadvantages are: inflexibility, complicated circuit implementation, and need to be re-edited once errors occur in the design. [0005] Therefore, there is a need for a simple and fast technical solution for real-time switching ...
