LTC5507 100kHz to 1GHz RF Power Detector
U FEATURES DESCRIPTIO
■
Temperature Compensated Internal Schottky
The LTC®5507 is an RF power detector for applications
Diode RF Detector
operating from 100kHz to 1000MHz. The input frequency ■
Wide Input Power Range: –34dBm to 14dBm
range is determined by an external capacitor. A tempera- ■
Ultra Wide Input Frequency Range: 100kHz to
ture-compensated Schottky diode peak detector and buffer
1000MHz
amplifier are combined in a small 6-pin ThinSOT package. ■
Buffered Output
The RF input voltage is peak detected using an on-chip ■
Wide VCC Range of 2.7V to 6V
Schottky diode and external capacitor. The detected volt- ■ Low Operating Current: 550µA age is buffered and supplied to the VOUT pin. A power ■ Low Shutdown Current: <2µA saving shutdown mode reduces supply current to less ■ Low Profile (1mm) ThinSOTTM Package than 2µA.
