www.DataSheet4U.com LTC5507 100kHz to 1GHz RF Power Detector FEATURES s s s DESCRIPTIO s s s s s Temperature Compensated Internal Schottky Diode RF Detector Wide Input Power Range: –34dBm to 14dBm Ultra Wide Input Frequency Range: 100kHz to 1000MHz Buffered Output Wide VCC Range of 2.7V to 6V Low Operating Current: 550µA Low Shutdown Current: <2µA Low Profile (1mm) ThinSOTTM Package The LTC®5507 is an 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 are combined in a small 6-pin ThinSOT package. 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
