RF Power Detector
General Description
The MAX2209 is a wideband (800MHz to 2GHz) RF
power detector. It takes an RF signal from the directional
coupler at the input, and outputs a DC voltage propor-
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 to less
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.
