A line of coaxial threshold detectors designed for microwave and millimeter wave applications from 2 to 40GHz has been released by Pasternack. These threshold detectors are commonly used for analysing radar performance, leveling pulsed signal sources, AM noise measurements, system monitoring and pulsed RF measurements in ultra-broadband applications.
Pasternack’s latest release of threshold detectors consists of three unique models covering broadband frequency bands from 2 to 40GHz. Designs incorporate gain stages for higher dynamic range that cover input power levels ranging from -45 to 0dBm with a typical threshold variation over frequency of ± 0.5dB. One model supports a fixed threshold while the other two models support an adjustable threshold setting. All models feature a TTL compatible video output response which is ‘1’ when the RF signal is above the threshold setting and ‘0’ when it’s below the threshold setting.
Additional features of the new threshold detectors from Pasternack include rugged construction utilising compact packages with field replaceable SMA or 2.92mm connectors. These models are designed to meet MIL-STD-202F environmental conditions for temperature cycle, humidity, shock, vibration and altitude. The threshold detectors also boast extremely fast response times ranging from 45 to 100ns, maximum input power handling ranging from +10 to +17dBm, and have an operating temperature range of -55 to +85°C.
“These adjustable threshold detectors have the features and broadband performance that are particularly useful for designers who need to analyse critical signal response characteristics,” explains Tim Galla, Active Components Product Manager, Pasternack.
