Product Description
The DG009-M1 Activity Detection Units
(ADU) is a fast activity detection unit, which
provides an indication of RF signal presence
over the 2.0 to 6.0 GHz frequency range. The
ADU consists of a power divider followed by
two banks of 8 channel multiplexers, one on
each arm of the power divider.
The outputs of the multiplexers are terminated
in diode detectors followed by high-speed
video comparators providing 16 TTL digital
outputs indicating the RF channel with a valid
signal.
Each channel of the ADU has a separately
digitally programmable threshold of 32 levels
over a 16 dB window. This is valid for each of
the two selectable video bandwidths ( 10 MHz
or 5MHz).
All input and output data is latched such that
output data signals are present for a minimum
period of time.
The ADU has been designed such that, when RF
signals are present in the crossover regions of the
mulitplexers, only one of the two adjacent digital
channels
will
trigger
unambiguous indication of input frequency.

clear
The ADU has been designed for use in airborne
transport environments of –20 degC to +80 degC
and up to 50,000 feet altitude.
The ADU has a low false alarm rate, giving high
system reliability and probability of detection
when incorporated into typical Electronic
Support Measures (ESM) suites.
