Log Detectors

Pasternack log detectors (aka Logarithmic Detector) are active coaxial components that convert RF signal strength into proportional DC voltage at its output, also referred to as “video out”. Log detectors from Pasternack are most commonly used to monitor and measure signal strength from an RF source. Our RF and microwave log detectors are RoHS and REACH compliant.


Log detectors are available with SMA connectors only. Our log detectors have varying frequency capabilities ranging from 10 MHz to 3 GHz depending on type and style. These log detectors have a maximum input power rating of 10 dBm and a slope of approximately 40 mV/mW. Pasternack carries one variation of log detectors with a positive output bias.


The Pasternack facility certified to ISO 9001:2015 ships our log detectors from stock the same day you order them. Pasternack Enterprises offers the broadest and deepest inventory of RF and microwave components available.
