max2209ebs+
Description
Rf Power Detector
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
19-4946; Rev 0; 10/09
The MAX2209 is a wideband (800MHz to 2GHz) RF
power detector. It takes an RF signal from the directional
coupler at the input, and
tional to the RF peak voltage. The change in output
voltage versus temperature is very repeatable from part
to part and enables a lookup table based on nominal
behavior, minimizing the effective detection error
than Q0.5dB relative to room temperature.
The MAX2209 comes in a space-saving 2 x 2, 0.5mm
pitch wafer-level package (WLP) and requires only two
external components.
