HMC1120LP4E

HMC1120LP4E is an RMS power detector with an integrated high bandwidth envelope detector. The RMS output is a temperature compensated, monotonic, linear-in-dB representation of real RF signal power, measured over an input sensing range of 70dB. The envelope detector provides an accurate voltage output which is linearly proportional to the amplitude envelope of the RF input signal for modulation bandwidths up to 150MHz. The high bandwidth envelope detection of this makes it ideal for detecting broadband and high crest factor RF signals commonly used in GSM, WCDMA, and LTE systems. Typical application includes Log –<gt/> root-mean-square (RMS) conversion, Tx/Rx signal strength indication, RF power amplifier efficiency control, receiver automatic gain control, transmitter power control, envelope tracking, PA linearization.
