Apr 17, 2018 · 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 …

Apr 14, 2024 · 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 …

Jan 31, 2017 · There are various types of bus couplers (for double bus system, single section bus system, etc.). I know that bus coupler between two busbars is called cross bus coupler. How …

Aug 26, 2023 · If a directional coupler is labeled 5-1002 Mhz, what happens to frequencies above that? Is that just the rated frequencies but above that may work fine, or does that mean it …

From what I understand, my opto-coupler should be fast enough, so that it can transmit the narrowest pulse (1% duty cycle), which has a duration of 1% * (1/1000) = 10 μs. …

Opto-isolators are designed to switch a small amount of current. A solid-state relay typically contains an opto-isolator along with some circuitry to switch a large amount of current in …

Jun 24, 2022 · I'm working on a project which uses a PCBA which basically acts as a USB-C extension. It has 2 USB-C receptacles (female) connectors. The mapping between the two …

Feb 9, 2025 · As long as the opto-coupler doesn't introduce a huge phase shift, causing feedback to get precariously close to becoming positive, or isn't asked to produce output current or …

May 9, 2023 · I am trying to make a circuit that measures 10-30V DC with isolation. The measurement is done by the circuit, not manual. The measured voltage level/information is …
