LTC5582IDD#PBF Overview

IC detector RF pwr 10ghz 10-dfn

DEMO CIRCUIT 1528A
LTC5582
QUICK START GUIDE
LTC5582
40 MHz to 10GHz RMS Power Detector
with 60dB Dynamic Range
DESCRIPTION
Demonstration circuit 1528A is a Mean-Squared Power
Detector featuring the LTC
®
5582 IC.
The LTC5582 is a wide dynamic range Mean Squared
RF Power Detector, operational from 40MHz to 6GHz.
The input dynamic range with ±1dB nonlinearity is
60dB depending on frequency(from –58dBm to
+2dBm, single-ended 50Ω input). The detector output
voltage slope is normally 30mV/dB, and the typical
output variation over temperature is ±0.5dB at
2140MHz.
The DC1528A Demo Circuit is optimized for wide fre-
quency range of 40MHz to 5.5GHz. However, input
match can be optimized above 6GHz with simple ex-
ternal matching. Operating above 6GHz is possible
with reduced performance. Contact applications for
more information.
Design files for this demo board are available. Call
the LTC factory.
