Product Information

19-4982; Rev 0; 10/09 KIT ATION EVALU ABLE 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.

For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial. Note 2: Refer to Application Note 1891: Wafer-Level Packaging (WLP) and Its Applications. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. CAUTION! ESD SENSITIVE DEVICE DC ELECTRICAL CHARACTERISTICS (VCC = 2.5V to 4.2V, TA = -40°C to +85°C, VENA = 2.7V, no RF signal applied. Typical values are at VCC = 2.8V, TA = +25°C, unless otherwise noted.)
