GENERAL DESCRIPTION

The RH5596S-CSH is a high accuracy RMS power detector that

provides a very wide RF input bandwidth, from 100 MHz up to

40 GHz. 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 29 mV/dB logarithmic slope over a 35 dB

dynamic range with typically better than ±1 dB accuracy over the

full operating temperature range and RF frequency range, from

200 MHz to 30 GHz. In addition, the device’s response has ±1dB

flatness within the frequency range of 200 MHz to 30 GHz. The

detector is particularly suited for measurement of waveforms with

crest factor (CF) as high as 12 dB, and waveforms that exhibit a

significant variation of the CF during measurement.

To achieve higher accuracy and lower output ripple, the averaging

bandwidth can be externally adjusted by a capacitor connected

between the FLTR pin and OUT pin.

The enable interface switches the device between an active meas-

urement mode and a low-power shutdown mode.

Additional application and technical information can be found in the

Commercial Space Products Program brochure and the LTC5596
