LTC5597

100MHz to 70GHz

Linear-in-dB RMS Power Detector with

35dB Dynamic Range

FEATURES

DESCRIPTION

TheLTC^®5597isahighaccuracyRMSpowerdetectorthat

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.

Ultra Wide Matched Input Frequency Range:

100MHz to 70GHz

35dB Linear Dynamic Range (< 1dB ꢀrrorꢁ

28.5mV/dB Logarithmic Slope

2dB Flat Response ꢂrom 100MHz to ꢃ0GHz

Accurate RMS Power Measurement oꢂ High Crest

Factors (Up to 12dBꢁ Modulated Waveꢂorms

Low Power Shutdown Mode

Low Supply Current: 33mA at 3.3V (Typical)

Small 2mm × 2mm Plastic DFN8 Package

I-Grade: −40°C to 105°C Rated

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

logarithmicslopeovera35dBdynamicrangewithtypically

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 sig-

nificant variation of the crest factor during measurement.

H-Grade: −40°C to 125°C Rated

with Guaranteed Log-Slope and Log-Intercept

ESD Rating: 2500V HBM, 1500V CDM

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.

APPLICATIONS

Point-to-Point Microwave Links

SATCOM

The enable interface switches the device between active

measurement mode and a low power shutdown mode.
