- coupling - What does an RF coupler actually do? - Electrical . . .
To start with, I've had difficulty finding a good, simple explanation of what directional coupling is I read through Radio Electronics, but the section on directional couplers doesn't give an overview of what it means to "couple " Could someone offer a simple explanation of what "coupling" is and what a directional coupler actually does?
- RF Directional Coupler - Electrical Engineering Stack Exchange
Directional coupler from here: - Coupling Loss - Amount of power lost to the coupled port (3) and to the isolated port (4) Assuming a reasonable directivity, the power transferred unintentionally to the isolated port will be negligible compared to that transferred intentionally to coupled port Main line loss - Resistive loss due to heating (separate from coupling loss) This value is added
- microwave - Dual directional coupler schematic? - Electrical . . .
I am new to microwaves I am trying to design a dual directional coupler using ADS software, but researching dual directional coupler isn't working; all that's showing is directional couplers and bi-
- Why use an opto-coupler? - Electrical Engineering Stack Exchange
When shit happens, like when things are fried, opto-coupler would keep things isolated while everything else has the possibility of bridging the low side to the high side Like if the transformer over heats and insulation breaks, then your whole low side is gone
- How reliable is using couplers to extend Ethernet cables?
I want to obtain one 90 meters of Ethernet CAT6 cable (with RJ45 connectors) by using three 30 meters of CAT6 cables with RJ45 connectors The only option I could find is to use three such couplers
- How does this HF coupler work? - Electrical Engineering Stack Exchange
I came across this coupler design in this link in another question It's designed to be used to couple a small monitoring amount of signal off a 1 kW HF (3 MHz to 30 MHz) signal on a through line
- Difference between RF splitter and coupler? - Electrical Engineering . . .
Somebody suggested using a splitter for this work, but when I tested one I found that all three nodes could communicate with each other Now, somebody is telling me to use a coupler Can a coupler achieve what I want? What is the difference between splitter and coupler? PS: I am working in the 2 4GHz band (wifi), if that makes a difference
- wave - How does an swr meter directional coupler work? - Electrical . . .
4 How does the directional coupler in an swr meter work? How are the forward and reflected waves separated out from the standing wave on the feeder? I would like an answer in terms of sine (or cosine) waves, phasors and complex numbers, as well as a non-mathematical description please
