The LT5534 is a 50MHz to 3GHz RF power detector with a dynamic range of 60dB. It features exceptional accuracy over temperature and power supply, fast transient response, and can be used for RF power detection, optical receiver gain control, etc.
The LT5534 RF power detector operates from 50 MHz to 3 GHz and provides a linear 60 dB dynamic range with high accuracy over temperature. It converts RF power to a log‑linear DC voltage (2.7 V‑5.25 V supply) suitable for RSSI, power control, and CATV applications.
Typical performance includes a 30 MHz output bandwidth, 200 ns turn‑on time, and low supply current (7 mA) with a shutdown current of 0.1 µA. The device is supplied in a 6‑lead SC70 package and offers pin‑compatible functions for enable, ground, output, supply, and RF input.
