Threshold Detector 10 to 2000 MHz Technical Data UTD-2004 Features Description Pin Configuration • Frequency Range: 10 to 2000 MHz The UTD-2004 is a sensitive microwave threshold detector which provides efficient and accurate RF level measurement at critical system points. It contains a planar tunnel diode detector, precision integrated circuit operational amp, comparator, and a temperature compensated voltage reference assembly. The unit is built with chip and wire construction on a thin-film substrate for small size and ruggedness.
