Logarithmic Detectors

Logarithmic Detectors are particularly suited to perform high dynamic range power measurements and are used in a wide range of automatic gain control and pulse detection applications. These devices produce a low frequency (DC) output that is logarithmically (“linear in dB”) related to the input signal level. ADI has an exceptionally broad portfolio of Logarithmic Detectors, operating from DC to 30GHz, with dynamic ranges up to 100dB, various package and bare die options, low-power optimized devices and much more. Our Logarithmic Detectors are used in a broad range of applications such as Transmit Power Control, Received Signal Strength Indicators (RSSI), Input Protection, Return Loss Measurement, Pulse Detection, and Precise RF Power Measurement in Test and Measurement, Materials Analysis and Medical applications.
