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?
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
90° hybrid coupler (Quarter-wave branch line hybrid) according to quot;Foundations for Microwave Engineering quot; by Robert E Collin, Lumped Element Quadrature Hybrids quot; by D Andrews and several others this is what a Quarter-wave branch line
high voltage - What types of bus couplers exist? - Electrical . . . A bus coupler is just a normal circuit breaker (and isolators), no matter where it's installed, or which busses it's connecting A "cross bus coupler" is just a bus coupler that happens to be connecting the two busses of a double-bus switchyard It's not a different type of switchgear and shouldn't be classified as such
6N137 opto-coupler with AC input takes a lot of time to trigger This is due to the time the AC input takes to reach the specified threshold values for the opto-coupler Note that when testing the optocoupler with a Step input it works perfectly How can I speed up the input without damaging the device? Here is an image of the measurement: Green is AC input, yellow is opto output Here is the test circuit
