Functional Diagram
General Description
The HMC614LP4E RMS 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 sig-
nal. The output is a temperature compensated, mono-
tonic representation of real signal power, measured
with a differential input sensing range of 71 dB.
The HMC614LP4E 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.
The HMC614LP4E provides an indication of the in-
stantaneous or peak input power level normalized to
the average input power level (peak to average power
ratio) via the IPWR output. The capability of simultane-
ously measuring the instantaneous power (envelope
power) and the average true RMS power provides
crucial information about the RF input signal: Peak
Power, Average Power, Peak to average power and
RF Wave-Shape.

The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
