33330B/8472B Coaxial Detectors
技术概述
The Keysight Technologies, Inc. 33330B/8472B broadband coaxial detectors are widely used in applications such as the detecting element in leveling loops, power monitoring, and as wideband video detectors.
These detectors use a Low-Barrier Schottky Diode (LBSD), specially fabricated with low origin resistance and low junction capacitance. This results in improved broadband flatness and SWR over point-contact diode detectors, thus yielding more accurate measurements. These detectors also offer very good ruggedness and burnout protection. As with all Keysight detectors, these models integrate the diode with the other circuit elements thus minimizing stray reactance’s and optimizing broadband performance.
In addition to superior RF characteristics, the LBS detector offers significant advantages over other types of detectors. For example, a typical Schottky requires bias for proper operation; a tunnel diode detector has a limited power range because of its negative resistance region; and the point contact diode, because of its fragile construction, is unsuitable for many field applications.
