Embodiment 1
[0019] Such as figure 2 As shown in the figure, the task channel configuration type high-power signal switching device connected with ten transmitting devices and ten transmitting antennas, the number of signal channels is the maximum number of simultaneous transmitting tasks in daily communication, because the maximum number of simultaneous transmitting tasks in daily communication is much smaller than The number of transmitting devices or transmitting antennas, there are three task channels in this embodiment, each task channel is provided with a connecting line with the output of each transmitting device and the input of each transmitting antenna, and each connecting line is provided with a radio frequency signal switches, the number of radio frequency signal switches is (10+10)×3=60, which significantly reduces the number of radio frequency signal switches used, improves reliability, and reduces costs. In addition, compared with the existing antenna switching device, in t...

The invention discloses a task channel configuration type high-power signal switching device, which is connected with a plurality of transmitting devices and a plurality of transmitting antennas, comprising a plurality of task channels, wherein, each task channel is connected with an output end of each transmitting device and an input end of each transmitting antenna through a connecting line, andeach connecting line is provided with a radio frequency signal switch; and the task channel is connected with an output end of each transmitting device and an input end of each transmitting antenna through a connecting line through a connecting line. A task channel configuration type high-power signal switch device of the invention has simple structure, the connection channel between the transmitting equipment and the transmitting antenna is simplified, and the use quantity of the radio frequency signal switch is reduced. When in use, the communication transmitting task can be allocated to the task channel first, and then the transmitting equipment and the transmitting antenna are configured to the task channel, so as to realize the high-power signal transmitting task. Compared with the prior art, the invention overcomes the shortcomings of the prior antenna switching device such as large volume, complex structure, low reliability, low utilization rate and high cost.
Description
technical field [0001] The invention relates to a high-power radio frequency signal switching device, in particular to a task channel configuration type high-power signal switching device. Background technique [0002] At present, large-scale wireless communication transmission stations are often equipped with a large number of wireless communication transmission equipment and transmission antennas. According to the equipment status and the specific needs of communication transmission tasks, specific transmission equipment and specific transmission antennas are connected to complete the scheduled communication. Launch mission. In order to realize the switching connection between multiple communication transmitting devices and transmitting antennas, the communication station needs to be equipped with a multi-channel antenna switching device. A high-power signal switching device usually consists of a high-power radio frequency signal switch and wiring to form a radio frequenc...
