The so-called RF switch on the market is not our traditional sense of the switch, it is not able to control the opening and closing of the circuit or close, but can control the communication information to a certain extent, for example, it can control the cable television network or the signal in the field of communication. In addition to different according to the actual situation also supports personalized customization, and its advantages are also very obvious, that is, a wider range of uses and lower costs, lower power consumption level and easy to install and so on. In addition, we found that it can also be used in the dialing of telephone switching or cable television signal switching, so it is a very valuable tool.
One, the role of the RF switch
RF switch, belonging to the cable television network or communication field with the signal switch, used for wired transmission of RF signals through the control, by the shell and two crystal diodes and auxiliary circuits connected to the input, output, and control terminals, a crystal diode in series in the AC signal channel, and the other diode connects the signal channel with the AC signal channel, and the other diode connects the signal channel with the AC signal channel. The other diode connects the signal channel with the AC signal ground, has the advantages of simple structure, wide range of use, low cost, low power consumption, easy to install, high reliability, etc., can be widely used in the field of carrier telephone switching, cable TV signal switching, cable TV signal switching.
Two, RF switch chip manufacturers recommended
