产品描述

The HMC1021LP4E 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 envelope amplitude of the RF input signal for modulation bandwidths up to 150 MHz. The high bandwidth envelope detection of the HMC1021LP4E makes it ideal for detecting broadband and high crest factor RF signals commonly used in CDMA2000, WCDMA, and LTE systems. Additionally, the instantaneous envelope output can be used to create fast, excessive RF power protection, PA linearization, and efficiency enhancing envelopetracking PA implementations.

The HMC1021LP4E’s RMS detector integration bandwidth is digitally programmable via input pins SCI1-4 over a range of more than 4 decades. This allows the user to dynamically set the operation bandwidth and also permits the detection of different types of modulations on the same platform.

The HMC1021LP4E features an internal op-amp at the RMS output stage, which accommodates slope and intercept adjustments and supports a wide range of applications.
