HMC713LP3E
General Description
Features
Functional Diagram
The HMC713LP3E Logarithmic Detector/Controller
is ideal for converting the power of RF signals with
frequencies in the 50 MHz to 8000 MHz range, to a
DC voltage, proportional to input power, at its output.
The HMC713LP3E employs a successive compression
technology which delivers 54 dB of dynamic range
with high measurement accuracy over a wide input
frequency range. As the input signal is increased,
successive ampliers move into saturation one by one
creating an accurate approximation of the logarithm
function. The outputs of a series of detectors are
summed, converted into voltage domain and buffered
to drive the OUTP output.
For detection mode, the OUTP pin is connected to
the VSET input and will provide a nominal logarithmic
slope of 17 mV/dB and an intercept of -68 dBm. The
HMC713LP3E can also be used in the controller mode
where an external voltage is applied to the VSET pin to
create an AGC or APC feedback loop.
Wide Dynamic Range: up to 54 dB
High Accuracy:
±1 dB with 54 dB Range Up To 2.7 GHz
Fast Output Response Time
Supply Voltage: +2.7 to +5.5V
Power-Down Mode
Excellent Stability over Temperature
16 Lead 3x3 mm SMT Package: 9mm
