1 LTC559615596fFor more information applicaTion FeaTuresDescripTion100 MHz to 40 GHz Linear-in-dB RMS Power Detector with 35dB Dynamic RangeThe LT C 5596 is a high accuracy RMS Power detector that provides a very wide RF input bandwidth, from 100 MHz up to 40 GHz. This makes the device suitable for a wide range of RF and microwave applications, such as point-to-point microwave links, instrumentation and Power control DC output voltage of the detector is an accurate rep-resentation of the average signal Power applied to the RF input . The response is Linear-in-dB with 29mV/dB logarith-mic slope over a 35dB dynamic range with typically better than 1dB accuracy. The detector is particularly suited for measurement of waveforms with crest factor (CF) as high as 12dB, and waveforms that exhibit a significant variation of the crest factor during the achieve higher accuracy and lower output ripple, the averaging bandwidth can be externally adjusted by a ca-pacitor connected between the FLTR and OUT enable interface switches the device between active measurement mode and a low Power shutdown to 40 GHz RMS Power DetectorOutput Voltage vs FrequencyapplicaTionsL, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
