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.
