LMH2100 50 MHz to 4 GHz 40 dB Logarithmic Power Detector

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 compensated 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 po.
