High Reliability, High Isolation Single-Pole-Double-Throw RF switch
https://www.electronics-lab.com/high-reliability-high-isolation-single-pole-double-throw-rf-switch/
In telecommunications, ideal RF switches require low insertion loss, high isolation and linearity. The IDT F2912 is a single-pole-double throw RF switch capable of having low insertion of loss of 0.4dB at 1GHz and a RF1 to RF2 Isolation of 74dB at 1GHz with extended temperature of -55C to +125C making it highly reliable. In […]

https://www.electronics-lab.com/turn-your-lights-on-with-clapping/
by GreatScottLab @ instructables.com: Wouldn’t it be nice to turn on your lights without getting off the couch? In this project I am going to show you how to build a simple Arduino clap circuit which can turn on and off all kinds of AC appliances. Let’s get started! Turn your lights on with clapping? – […]
Even you switch ecologically?
https://www.electronics-lab.com/even-you-switch-ecologically/
More exactly, we talk about switching-off a device. Marquardt 1550 Eco Switch enables this extraordinarily easily. Do you know a situation, when a seemingly usual thing is fact not that usual… Whether it´s a car with a hybrid drive or a lot of devices which we meet every day – usually in every segment can […]
