Thank you, Moderator! I will ask Moderator for advice (6)[Copy link]
Thank you, moderator. I have another question for you. It would be a bother for you. The connector of coaxial cable can be replaced, but not all models can be replaced. What about coaxial line? What kind of connecting wire (other than coaxial cable) is suitable for connecting the microwave devices I mentioned before? The connector of the connecting wire must be selected according to the connector of the device, but will there be a situation where you can't find a connecting wire with a suitable connector (it doesn't match the connector of the device)? The bandwidth of the isolator is not what the moderator said. From the information provided by the manufacturer on the Internet, the bandwidth is smaller than the difference between the maximum and minimum values of the frequency range. How to explain it? In what cases do you need to use a low-noise amplifier instead of a power amplifier? Why?
Microwave devices can be connected with semi-rigid coaxial cables, which seems to be used by most. Sometimes the connector of the device is different from the cable connector. You can consider using an adapter or transition device, but this will affect the standing wave. It is better to use one that can be used directly. The maximum and minimum values are the ranges that the device can withstand or not be damaged, while the working bandwidth is the range of guaranteed indicators. Most of the working bandwidth will be smaller than the difference between the two. The front stage of the system is used to amplify weak signals with a low noise amplifier, and the intermediate stage and later can use a power amplifier.
