LT5538

40MHz to 3.8GHz

RF Power Detector with

75dB Dynamic Range

FEATURES

DESCRIPTION

The LT^®5538 is a 40MHz to 3800MHz monolithic logarith-

mic RF power detector, capable of measuring RF signals

over a wide dynamic range, from –75dBm to 10dBm. The

RF signal in an equivalent decibel-scaled value is precisely

convertedintoDCvoltageonalinearscale. Thewidelinear

dynamic range is achieved by measuring the RF signal us-

ing cascaded RF limiters and RF detectors. Their outputs

are summed to generate an accurate linear DC voltage

proportional to the input RF signal in dBm. The LT5538

delivers superior temperature stable output (within 1dB

over full temperature range) from 40MHz to 3.8GHz. The

output is buffered with a low impedance driver.
