Advanced portable communication products require high-efficiency power amplifiers operating at low voltage. The size and weight of the portable units can be reduced markedly by decreasing the number ...

A case in point is this super-low-cost RF power sensor that [Tech Minds (M0DQW)] recently built. It’s based on a design by [DL5NEG] that uses a single Schottky diode and a handful of passive ...

RF Power classification defines the RF power levels associated with specific modes of operation for a particular class of radio device. Classes of RF devices often vary based on the application and ...

You’ll find it at the heart of an RF power meter, but it’s also perfect for a precision field strength meter like this one. That movie spy would have a much higher chance of finding the bug ...
