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.
Factors (Up to 12dB) Modulated Waveforms
The DC output voltage of the detector is an accurate rep- n

The response is linear-in-dB with 29mV/dB logarith- n Small 2mm × 2mm Plastic DFN8 Package mic slope over a 35dB dynamic range with typically better n I-Grade: –40°C to 105°C Rated than ±1dB accuracy. The detector is particularly suited for H-Grade: –40°C to 125°C Rated measurement of waveforms with crest factor (CF) as high with Guaranteed Log-Slope and Log-Intercept as 12dB, and waveforms that exhibit a significant variation n ESD Rating: 3500V HBM, 1500V CDM of the crest factor during the measurement.
