Description
The UTD-1000 has an input
impedance of 50 ohms. The
UTD-1001 has an input impedance
of greater than 300 ohms. In all
other respects the detectors are
similar. The level detector con-
sists of an amplifier stage that
drives a Schottky-barrier detector
diode. Matched back-to-back
silicon diodes which are closely
thermally-coupled to the detector
provide a DC tracking reference.
