LTC5596
100MHz to 40GHz
Linear-in-dB RMS Power Detector with
35dB Dynamic Range
DescripTion
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 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 measurement.
To achieve higher accuracy and lower output ripple, the
averaging bandwidth can be externally adjusted by a ca-
pacitor connected between the FLTR and OUT pins.
The enable interface switches the device between active
measurement mode and a low power shutdown mode.
