LTC5507ES6#TRPBF

LTC®5507 is a RF power detector for applications operating from 100KHz to 1000MHz. The input frequency range is determined by an external capacitor. A temperature-compensated Schottky diode peak detector and buffer amplifier. The RF input voltage is peak detected using an on-chip Schottky diode and external capacitor. The detected voltage is buffered and supplied to the VOUT pin. A power saving shutdown mode reduces supply current to less than 2µA. Application includes wireless transceivers, wireless and cable infrastructure, RF power alarm, envelope detector.
