Active: In Production.

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 proportional 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 ±0.5dB 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.
