HMC713LP3E 射频检测器

HMC713LP3E

射频检测器 Log Amp, lo Dyn ring 100-2700MHz

54 dB, LOGARITHMIC  DETECTOR / CONTROLLER, 50 - 8000 MHz

General Description

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 amplifiers 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.

Typical Applications
