Log Detectors

ADI’s Log Detectors measure signal levels at frequencies from dc to microwave. These devices provide an accurately-scaled dc output voltage which is proportional to the log of the input signal. With detection ranges up to 100 dB, our log detectors are used in a range applications such as Transmit/Receive Power Measurement, Input Protection, Return Loss Measurement, Pulse Detection, Electronic Warfare and Precise RF Power Measurement in Test and Measurement, Materials Analysis and Medical applications.
