Crane Aerospace & Electronics Microwave RF BIT Module O-DET-2116

The O-DET-2116 RF BIT Module provides several integrated functions for detection and measurement of RF levels. The unit consists of an internal temperature compensated RF detector. This rectifi es the RF signal and produces a dc level from the input signal. The diode output feeds a sample and hold circuit, which allows the unit to capture and hold a narrow RF pulse, consistent with a radar signal. The sampled output feeds two threshold detectors, which can be set for minimum and maximum levels. Applications of this detector include level detection and VSWR protection for amplifi ers and other sensitive circuits. Combining two of these units with a dual directional coupler can be used as a VSWR threshold trigger so that an amplifi er is not damaged by excess reverse power. Alternate confi gurations can be built to specifi c requirements. Please contact Olektron sales to discuss your specifi c requirements.
