LMH2100 50 MHz to 4 GHz 40 dB Logarithmic Power Detector for CDMA and WCDMA .. November 28, 2007 LMH2100 50 MHz to 4 GHz 40 dB Logarithmic Power Detector for CDMA and WCDMA General Description The LMH2100 is a 40 dB RF power detector intended for use in CDMA and WCDMA applications. The device has an RF frequency range from 50 MHz to 4 GHz. It provides an accurate temperature and supply pensated output voltage that relates linearly to the RF input power in dBm. The circuit operates with a single supply from 2.7V to 3.3V. The LMH2100 has an RF power detection range from - 45 dBm to - 5 dBm and is ideally suited for direct use in bination with a 30 dB directional...
