MAX2209

19-4946; Rev 0; 10/09 TION KIT EVALUA BLE IL AVA A RF Power Detector Features S -25dBm to 0dBm Power Detection Range S ±0.5dB Detection Error Due to Temperature S +2.7V to +5V Single-Supply Operation S Space-Saving 4-Bump, 1mm2 UCSP™ Package S On-Chip 50I Termination and DC-Blocking 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 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 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.
