Embodiment Construction

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a co-existence of an intervening component. When a component is considered to be "set on" another component, it ...

Abstract

The invention relates to the technical field of wireless communication equipment testing, and discloses a radio frequency mode switch compatible with multiple channel simulators, which comprises an uplink signal interface, a downlink signal interface, a first channel interface, a second channel interface, a third channel interface, a first switch, a second switch and a third switch, the first switch, the second switch and the third switch are all single-pole double-throw switches; the fixed end of the first switch is connected with the uplink signal interface, and two movable ends of the first switch are respectively connected with the first channel interface and one movable end of the second switch; the other movable end of the second switch is connected with the second channel interface, and the fixed end is connected with one movable end of the third switch; the other moving end of the third switch is connected with a downlink signal interface, and the fixed end of the third switch is connected with a third channel interface; the radio frequency mode switch compatible with multiple channel simulators can be suitable for channel simulators in three different modes, namely a two-channel one-way mode, a single-channel two-way mode and a single-channel one-way mode, the design cost of the radio frequency mode switch is reduced, and the equipment debugging time is saved.

Description

technical field [0001] The invention relates to the technical field of wireless communication equipment testing, in particular to a radio frequency mode switch compatible with multiple channel emulators and a wireless communication testing system. Background technique [0002] Wireless devices undergo extensive testing to ensure that their performance meets communication requirements before they go to market. In order to effectively shorten the research and development cycle of wireless products and reduce the cost of testing, channel emulators that can simulate the real wireless channel propagation environment in the laboratory environment emerge as the times require. At present, the wireless channel modes of channel emulators designed by different manufacturers are basically divided into three types, mode 1 is a dual-channel unidirectional channel simulator, mode 2 is a single-channel bidirectional channel simulator, and mode 3 is a single-channel unidirectional channel si...
