  Detectors
 
Spectrum Microwave produces temperature compensated detectors, which operate from 10 MHz to 2 GHz. Analog/Level Detectors convert a range of RF input powers (typically from -20 dBm to +10 dBm) to a corresponding DC output voltage level. Threshold Detectors, using an external resistor or threshold voltage, output a TTL compatible signal when the RF level exceeds the preset threshold.
