Functional Diagram
General Description
The HMC909LP4E Power Detector is designed for
RF power measurement, and control applications for
frequencies up to 5.8 GHz. The detector provides
an accurate RMS representation of any broadband,
single-ended RF/IF input signal. The output is a tem-
perature compensated monotonic, representation of
real signal power, measured with an input sensing
range of 40 dB.
The HMC909LP4E 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 HMC909LP4E is
digitally programmable with the use of input pins
SCI1-4 with a range of more than 4 decade. This
allows the user to dynamically set the operation
bandwidth providing the capability of handling differ-
ent types of modulations on the same platform.
HMC909LP4E features an internal op-amp at output
stage, which provides for slope / intercept adjustments
and enables controller application.
