The LTC5597 from Analog Devices is a Linear-in-dB RMS power detector with a 35dB dynamic range. The LTC5597 is a high accuracy RMS power detector that provides a very wide RF input bandwidth, from 100MHz up to 70GHz. 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 applications.
The DC output voltage of the detector is an accurate representation of the average signal power applied to the RF input. The response is linear-in-dB with 28.5mV/dB logarithmic 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 measurement. Applications include Point-to-Point Microwave Links, SATCOM, Instrumentation and Measurement Equipment, Military Radios, 5G, LTE, WiFi, Wireless Networks and more.
