LTC5596 Typical Application


The LTC®5596 is a high accuracy RMS power detector that provides a very wide RF input bandwidth, from 100MHz up to 40GHz. 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 29mV/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 the measurement.

To achieve higher accuracy and lower output ripple, the averaging bandwidth can be externally adjusted by a capacitor connected between the FLTR and OUT pins.

The enable interface switches the device between active measurement mode and a low power shutdown mode.
