ADI HMC1120LP4ETR

0 Гц ~ 3,9 ГГц-60 дБм ~ 8 дБм

Overview

The HMC1120LP4ETR 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 70 dB. 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 150 MHz. The high bandwidth envelope detection of the HMC1120LP4ETR makes it ideal for detecting broadband and high crest factor RF signals commonly used in GSM, WCDMA, and LTE systems. Additionally, the instantaneous envelope output can be used to create fast, excessive RF power protection, PA linearization, and efficiency enhancing envelope-tracking PA implementations.

The HMC1120LP4ETR features an internal op-amp at the RMS output stage, which accommodates slope and intercept adjustments and supports a wide range of applications.
