I don't have the circuit, but the RSS output of these beasties tends to b=
e a=20
current output. The output pin likes to live at 5V. A simple opamp circui=
t=20
can do the I to V conversion (as it does in the Ultra sniffer with the 33=
62).
It's actually a measure of the current going into the limiter stages, and=
 the=20
datasheet (google) has a graph of I V's dB.

--=20
