5596 TA01a LTC5596 100MHz to 40GHz Linear-in-dB RMS Power Detector with 35dB Dynamic Range Fea T Descrip T n Ultra Wide Matched Input Frequency Range: The LTC 5596 is a high accuracy RMS power detector that 100MHz to 40GHz provides a very wide RF input bandwidth, from 100MHz n 35dB Linear Dynamic Range (< 1dB Error) up to 40GHz. This makes the device suitable for a wide n 29mV/dB Logarithmic Slope range of RF and microwave applications, such as point- n 1dB Flat Response from 200MHz to 30GHz to-point microwave links, instrumentation and power n Accurate RMS Power Measurement of High Crest control applications.
