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 a
“true RMS” representation of any RF/IF input signal.
The output is a temperature compensated monotonic,
representation of real signal power, measured 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.

High pass filter capacitor input. Connect a
capacitor between COFSA and COFSB to
determine 3 dB point of input signal high-pass filter.

VSET
Setpoint input for controller mode. Allows change
of output slope resulting in output power leveling.

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.
