MAX2203

19-4982; Rev 0; 10/09 KIT ATION EVALU E L B A AVAIL RMS Power Detector General Description The MAX2203 RMS power detector is designed to operate from 800MHz to 2.0GHz. The device is ideal for wideband code-division multiple access (WCDMA), cdma2000®, and high-speed downlink/uplink packet access. The MAX2203 accepts an RF signal at the input and outputs the same voltage regardless of the peak-average of the input signal. The output voltage and input power is linear in dB. The device has a -24dBm to +3dBm detection range, and every dB change in input power gives 35mV (typ) change in output voltage. The MAX2203 operates from a 2.5V to 4.2V supply and is specified over the -40°C to +85°C extended temperature range. The device is available in a 6-bump WLP package. o 35mV/dB (typ) Log Detector o 0.1dB (typ) RMS Accuracy from WCDMA Modulation Change o ±0.4dB Detection Error Due to Temperature o +2.5V to +4.2V Single-Supply Operation o Space-Saving 6-Bump WLP Package Features o -24dBm to +3dBm Power-Detection Range MAX2203 Ordering Information PART MAX2203EWT+T10 TEMP RANGE -40°C to +85°C PINPACKAGE 6 WLP TOP MARK AA Applications WCDMA, cdma2000, 1xEVDO High-Speed Downlink Packet Access (HSDPA) High-Speed Uplink Packet Access (HSUPA) +Denotes a lead(Pb)-free/RoHS-compliant package.
