A measuring square-law diode detector

A general approach, circuit diagrams, and test results of a square-law detector with improved metrological characteristics are presented. The detector is based on a “diode + current-to-voltage converter” scheme. The measured characteristics are as follows: the dynamic range is 40 dB, and quadraticit...

Zusammenfassung:	A general approach, circuit diagrams, and test results of a square-law detector with improved metrological characteristics are presented. The detector is based on a “diode + current-to-voltage converter” scheme. The measured characteristics are as follows: the dynamic range is 40 dB, and quadraticity factor is 2.00 ± 0.05. The working frequency band of a particular detector is from 0.001 to 2 GHz. The proposed approach is suitable for detectors of most kinds (series, parallel, single- and two-cycle, etc.), operating in the radio frequency band.
