Planar-Doped Barrier Diode Detector, 0.01 to 33 GHz
8474C
Diode Detector
The Keysight 8474C is a high-performance detector using a gallium arsenide, planar-doped barrier detecting element. It features extremely flat frequency response over its entire band of operation and very good frequency response stability versus temperature. The Keysight 8474C is also very rugged with high resistance to ESD damage. The Keysight 8474C detector is available with a 3.5-mm (mates with SMA, 0.01 to 33 GHz) connector. This detector offers the options for optimal sqaure-law loads (Option 102) and for positive polarity output (option 103). Because the unit-to-unit frequency response tracking of this device is typically better than 0.3 dB, no matched response option is offered.

LIMITER P-I-N DIODES FROM 0.7 TO 9.55 GHz
-
They prevent failure of of input amplifying stage of low-noise receivers with radio pulse power up to 5000 Watt. They can also be applied as seperate units without power supply and acting as controlled switches. This component is very valuable for radar applications because the high power transmitter and extremely sensitive receiver work with a single antenna.

LIV – High-power Laser Diode Testing
-
An important aspect of the development and manufacture of laser diodes is the so-called laser diode characterization, or laser IV curve. By applying increasing current to the laser diode so it that emits light, the optical output is measured together with the voltage drop across the diode element. The resulting LIV curve reveals important clues about the quality of manufacture and the performance of the laser diode, enabling a pass/fail decision to be met.
