A directional coupler is used to sample a small amount of input signal power for measurement purposes. Port 1 is the input port; port 2 is the output port; port 3 is the coupled port; port 4 is the ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

Switching dc-dc power supplies are prolific in today's consumer electronics. Most applications use an input source that provides a positive dc voltage referenced to system ground. These sources often ...

Around the world, over 200 countries use Alternating current (AC) power as a convenient power source for many electronics. However, the power around the world is not the same in each location, ...

Some applications require a positive voltage to be generated from a negative input voltage. This can be done either by using a transformer based topology, such as a flyback converter, or with a ...
