423B

      Agilent offers a complete family of high performance Low Barrier Schottky Diode Detectors which cover the 10 MHz to 26.5 GHz frequency range. These 423B general purpose components are widely used for CW and pulsed power detection, leveling of sweepers, and frequencyresponse testing of other microwave components. These detectors do not require a dc bias and can be used with common oscilloscopes, thus their simplicity of operation and excellent broadband performance make them useful measurement accessories. These 423B 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 423B detectors also offer very good ruggedness and burnout protection. As with all Agilent detectors, these models integrate the diode with the other circuit elements thus minimizing stray reactances and optimizing broadband performance. For economical field repair, replaceable detector modules are available.
         423B has fice unique features. The first one is excellent broadband flatness. The second one is low broadband SWR. The third one is high burnout protection. The forth one is environmentally rugged. The fifth one is field replaceable diode elements.
        Then there are some specifications about 423B. Frequency range1 is from 0.01GHz to 12.4 GHz. Frequency response ,Octave band fl atness(over any octave 0 01 to 8 GHz), is ±0.2 dB. Broadband fl atness is from 0.01 dB to 12.4 GHz: ±0.3 dB. Maximum operating input(Peak or average) is 200 mW.Short- term maximum Input(less than 1 min) is 1 watt (typical).
Sensitivity4 is bigger than 0.5 mV/W. Output polarity is negative.
        423B can be used in a wide variety of applications ranging from lab and production measurements to systems components. Because of its fl atnessand match, these detectors can be used for accurately measuring transmission and refl ection characteristics in CW or swept-frequency measurements. Also , there are other applications and you will also finf 423B an excellent product.
