Functional Diagram
General Description
The HMC610LP4E Power Detector is designed for RF
power measurement, and control applications for
frequencies up to 3.9 GHz. The detector provides a
“true RMS” representation of any RF/IF input signal.
The output is a temperature compensated monotonic,
representation of real signal power, measured with a
differential input sensing range of 75 dB, or 72 dB of
single-ended sensing range.
The HMC610LP4E is ideally suited to those wide
bandwidth, wide dynamic range applications, requir-
ing repeatable measurement of real signal power,
especially where RF/IF wave shape and/or crest factor
change with time.
