Production Rf Tested, Rf Power Detector For Cdma And Wcdma - National Semiconductor

The LMV227 is a 30 dB RF Power detector intended for use in CDMA and WCDMA applications. The device has an RF frequency range from 450 MHz to 2 GHz. It provides an accurate temperature and supply compensated output volt- age that relates linearly to the RF input power in dBm. The circuit operates with a single supply from 2.7V to 5V. The LMV227 has an integrated Filter for low-ripple average power detection of CDMA signals with 30 dB dynamic range. Addi- tional filtering CAN be applied using a single external capaci- tor. The LMV227 has an RF Power detection range from -30 dBm to 0 dBm and is ideally suited for direct use in combi- nation with resistive taps. The device is active for Enable = HI, otherwise it goes into a low power consumption shut- down mode. During shutdown the output will be LOW. The output voltage ranges from 0.2V to 2V and CAN be scaled down to meet ADC input range requirements. The output signal bandwidth CAN optionally be lowered externally as well.
