Pasternack has introduced a new line of coaxial threshold detectors designed for microwave and millimeter wave applications from 2 GHz to 40 GHz. These threshold detectors are commonly used for analyzing radar performance, levelling pulsed signal sources, AM noise measurements, system monitoring and pulsed RF measurements in ultra-broadband applications.
This latest release of threshold detectors consists of 3 unique models covering broadband frequency bands from 2 to 40 GHz. Designs incorporate gain stages for higher dynamic range that cover input power levels ranging from -45 dBm to 0 dBm with a typical threshold variation over frequency of ± 0.5 dB. One model supports a fixed threshold while the other 2 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 these threshold detectors from Pasternack include rugged construction utilizing 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 100 nanoseconds, maximum input power handling ranging from +10 to +17 dBm, and have an operating temperature range of -55 to +85 degrees Celsius.
