RF Detectors
1. What are RF Detectors?
RF detectors are specialized devices used to measure RF signal power levels. They achieve this by converting RF input signals into DC or low-frequency output signals. Their core principles are based on:
Logarithmic amplifier technology (such as the AD8313);
Square-law detection (suitable for low-power scenarios);
Peak detection (for pulse signal analysis).
