RF environment automatic calibration device

Abstract

The invention discloses an RF environment automatic calibration device. The RF environment automatic calibration device comprises a box body which is internally provided with a power module, a main control module, a single-pole multi-throw coaxial mechanical RF switch module and a double-pole double-throw mechanical RF switch module; a display module, an external interface module, meter interfaces and RF environment interfaces are arranged at the outer sidewalls of the box body; the RF environment interfaces are connected with the single-pole multi-throw coaxial mechanical RF switch module; the single-pole multi-throw coaxial mechanical RF switch module is connected with the double-pole double-throw mechanical RF switch module through an RF wire; the single-pole multi-throw coaxial mechanical RF switch module and the double-pole double-throw mechanical RF switch module are connected with the main control module respectively; and the meter interfaces are connected with the double-pole double-throw mechanical RF switch module. Through controlling the switching action of the single-pole multi-throw coaxial mechanical RF switch module and the double-pole double-throw mechanical RF switch module, the RF environment automatic calibration device has the characteristics such as simple operation, convenient maintenance, high extendibility and high universality, and particularly is low in cost price and suitable for industrialization.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a radio frequency environment automatic calibration device. Background technique [0002] With the development of wireless communication technology, the functions of communication equipment are becoming more and more complex, and higher requirements are put forward for the radio frequency testing of wireless communication systems. Especially for 4G and 5G communication systems, the number of radio frequency indicators is large and the requirements for indicators are high. Multiple test environments need to be set up. Moreover, the number of antennas has increased from two antennas to four antennas, eight antennas, and even more than 64 antennas. During the test, the specific performance requirements in the wireless channel environment are higher each time. At present, the test system for measuring wireless devices in the channel environment basically adopts the...

Problems solved by technology

[0003] The existing baseband channel simulation test system, due to the need to add complex channel simulation algorithms, has high requirements on baseband software and hardware, which brings very expensive costs, and because the number of ports is limited by the baseband algorithm, it cannot provide enough ports to accurately Characterize the test limitations brought about by the differences between the ports of the communication equipment itself on the system, etc.
