DESCRIPTION
The LT®5538 is a 40MHz to 3800MHz monolithic logarithmic 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 converted into DC voltage on a linear scale. The wide linear dynamic range is achieved by measuring the RF signal using 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. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners. Frequency Range: 40MHz to 3.8GHz 75dB Log Linear Dynamic Range Exceptional Accuracy over Temperature Linear DC Output vs. Input Power in dBm –72dBm Detection Sensitivity Single-ended RF Input Low Supply Current: 29mA Supply Voltage: 3V to 5.25V 8-lead DFN 3mm × 3mm packageAPPLICATIONS
