IntroductionThe RF power meter is the key tool for calibration and quality control in my radio frequency projects.When working with RF equipment, we often need to know the output power of our system. This serves multiple purposes: from validating the state of the output to confirming that the transmission power is within a valid range (useful if we have to perform certification processes, for example).I arrived at this solution after analyzing various RF power measurement systems and finding one that was quite economical, functional, and very simple (without the need for any desktop applications).First, it's important to understand how RF system power measurement works. It's usually measured in Watts and indicates the amount of energy being transmitted/received per unit of time (1 W…
