DESCRIPTIO
®
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 tempera-
ture-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 volt-
age is buffered and supplied to the V
saving shutdown mode reduces supply current to less
than 2 A.
