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 a
“true RMS” representation of any broadband, single-
ended RF/IF input signal. The output is a temperature
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.

COFSA,
COFSB
High pass filter capacitor input. Connect a capacitor
between COFSA and COFSB to determine 3 dB
point of input signal high-pass filter.
14
VSET
Setpoint input for controller mode. Allows change of
output slope resulting in output power leveling.
15
RMSOUT
Logarithmic output that provides an
indication of mean square input power.

SCI1 - SCI4
Digitally Programmable Integration Bandwidth
Control. Input pins that control the internal
integration time constant for RMS calculation. SCI4
is the most significant bit. Set V>0.8xVcc to enable
and V<0.2xVcc to disable (active high). Shortest
integration time is for SCI=0000, longest integration
time is for SCI=1111. Each step changes the
integration time by 1 octave.
