General Descriptions
The HMC1020LP4E 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 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 72 dB.
The HMC1020LP4E 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 HMC1020LP4E is
digitally programmable with the use of input pins
SCI1-4 over a range of more than 3 decades. This
allows the user to dynamically set the operation
bandwidth and also permits the detection of different
types of modulations on the same platform.
HMC1020LP4E features an internal op-amp at the out-
Electrical Specifications I
put stage, which provides for slope / intercept adjust-
ments and enables controller application.

Input high pass filter capacitor. Connect a capacitor
between COFSA and COFSB to determine 3 dB

SCI1, SCI2,
SCI3, SCI4
Digital input pins that control the internal integration
time constant for mean square calculation. SCI4 is
the most significant bit. Set V>0.2xVcc to disable.
Shortest integration time is for SCI=0000, allowed
longest integration time is for SCI=1100 (1101, 1110
and 1111 SCI settings are forbidden states). Each
step changes the integration time by 1 octave.
