MAX2203
RMS Power Detector
Industry's Most Accurate RMS Power Detector over Input Power Range, Regardless of Modulation
Part Details
- -24dBm to +3dBm Power-Detection Range
- 35mV/dB (typ) Log Detector
- 0.1dB (typ) RMS Accuracy from WCDMA Modulation Change
- ±0.4dB Detection Error Due to Temperature
- +2.5V to +4.2V Single-Supply Operation
- Space-Saving 6-Bump WLP Package
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.
Applications
- High-Speed Downlink Packet Access (HSDPA)
- High-Speed Uplink Packet Access (HSUPA)
- WCDMA, cdma2000, 1xEVDO
