Embodiment Construction

[0016] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] see figure 1 The block diagram of the overall composition of the matrix RF switch intelligent switching control series and its figure 2 Shown is the software control flow chart. The present invention consists of a matrix switch unit 01, a monitoring board 02 pre-installed with intelligent control software, an OMT near-end / remote monitor 03, an N-way input device interface 04, an N optional N-3 output device interface 05, and an N optional three It is composed of 1-way output device interface 06 and power module 07. Among them, the matrix switch unit 01 is composed of 2N subunits, and each subunit is composed of N-1 single-pole double-throw radio frequency switches, and the subunits are connected to ports and between adjacent switch nodes through radio frequency cables; the N-1 A switch constitutes a radio frequency sw...

Abstract

The intelligent matrix type RF switch switching controller consists of matrix switch unit, monitoring board, OMT monitor, N-path input interface, N-path output interface and power supply. The NxN matrix switch unit consists of 2N sub-units, and each of the 2N sub-units consists of N-1 SPDT RF switches and is equivalent to one SPNT RF switch. The monitoring board controls the manual or automatic switching of the matrix switch intelligently based on the parameter setting in the monitor to complete the one-to-one signal transmission from any one of the N-path input interface to any optional one of the N-path output interface. There are high isolation degree between the signal channels and no mutual interference. The present invention has fast switching speed, high isolation degree, simple structure and intelligent control, and may be used to raise the system reliability and realize the fast switching of great power RF signal.

Description

Technical field [0001] The invention relates to a radio frequency switch, in particular to a series of radio frequency switches adopting matrix mode, capable of near-end or remote parameter selection or setting, and realizing intelligent switching control. Background technique [0002] The traditional radio frequency switch or switch array technology is single, the operator must manually connect the external equipment cables on site, or switch operations one by one separately, which is labor-intensive, time-consuming, unsafe, and difficult to switch in time; especially the traditional method It cannot meet the actual needs of fast, accurate and safe switching when performing emergency switching processing on high-power radio frequency. Contents of the invention [0003] The purpose of the present invention is to provide an improved radio frequency switch series that adopts matrix mode, can perform parameter selection or setting at the near end or remotely, and realizes int...
