20 dB Input Range • Transmitter Power Control Power Detectors -SMT 11 Envelope Detection Bandwidth > 150MHz • Envelope Tracking Digitally Programmable Integration Bandwidth • PA Linearization Power-Down Mode
24 Lead 4x4mm SMT Package: 16mm² Functional Diagram General Descriptions
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 …
