The
Maxim MAX2209A wide-band
(800MHz to 2GHz)
RF power detector
with shutdown control 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 room temperature. The
Maxim MAX2209A RF power detector
comes in a space-saving 2x2, 0.5mm pitch wafer-level package (WLP) and requires only two external components. The
MAX2209A
RF power detector
is targeted for use in a variety of applications, including dual-band WCDMA handsets, high-speed downlink packet access, and high-speed uplink packet access.
