General Description
The HMC1010LP4E Power Detector is designed for
RF power measurement, and control applications
for frequencies up to 3.9 GHz. The detector provides
an accurate RMS representation of any RF/IF input
signal. The output is a temperature compensated
monotonic, representation of real signal power, mea-
sured with an input sensing range of 60 dB.
The HMC1010LP4E 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 integration bandwidth of the HMC1010LP4E is
digitally programmable with the use of input pins SCI1-
4 with a range of more than 4 decades. This allows
the user to dynamically set the operation bandwidth
providing the capability of handling different types of
modulations on the same platform.
The HMC1010LP4E features an internal OP-AMP at
output stage, which provides for slope & intercept ad-
justments and enables controller application.
