LMV228TL/NOPB General Description

For engineers and designers in the telecommunications industry, the LMV225/LMV226/LMV228 power detectors present a powerful solution for accurate RF power detection in CDMA and WCDMA applications. With a wide RF frequency range encompassing 450 MHz to 2 GHz, these detectors offer superior precision and reliability. Operating on a single supply voltage ranging from 2.7V to 5.5V, the LMV225/LMV226/LMV228 provide a temperature and supply compensated output voltage that correlates directly to RF input power in dBm. The integrated filter ensures low-ripple average power detection of CDMA signals with a dynamic range of 30 dB. By utilizing an external capacitor, additional filtering can be implemented to enhance performance and customization options. The LMV225, tailored for power detection between -30 dBm to 0 dBm, is an ideal choice for resistive taps, while the LMV226 and LMV228, designed for detection ranges between -15. (continued
