Data Sheet
Features and Description
• Zero bias
• Environmentally rugged
• SMA connector
The Agilent 8471E Detector is a
Planar Doped Barrier (PDB) detector
offering the characteristics of the
Agilent 8474 line of PDB detectors in
an economical package. It is available
with an SMA RF connector and an
SMC video connector.
The detector is designed for use in RF
and microwave instrumentation and
systems applications as the detecting
element in leveling loops, for power
monitoring and for wideband video
detection.
