RF Power Detector
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
OUT
pin. A power
saving shutdown mode reduces supply current to less
than 2µA.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Specifications over the –40°C to 85°C operating temperature
range are assured by design, characterization and correlation with
statistical process controls.
Note 3: RF performance is tested at: 80MHz, –4dBm
Note 4: Guaranteed by design.
