LT5538 Datasheet 40MHz to 3.8GHz RF Power Detector

Manufacturer: Linear Technology (now Analog Devices)

Overview: LT5538 40MHz to 3.8GHz RF Power Detector with 75dB Dynamic Range www.DataSheet4U.

General 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.
