LV Iron Core Line & Load Reactors
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.

Broadband Detectors
These waveguide bandwidth detectors use silicon beam lead diodes on a planar stripline circuit to obtain an extremely rugged and compact device. Most millimeter wave broadband detectors have very poor VSWR due to the difficulty in obtaining a good wideband impedance match to the diode. To overcome this problem, these detectors utilize two diodes and an internal matched termination and 3 dB hybrid as shown below. This circuit allows a VSWR of 2.0 or better over a full waveguide bandwidth for most of these detectors. Detectors for waveguides WR-8 and smaller use a single zero bias GaAs diode. The high sensitivity zero bias GaAs diodes can also be special ordered for use at lower frequencies when highest sensitivity is required.

Shunt Voltage References
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.

Deep Submersible Particle Size Analyzer
LISST-Deep
The LISST-DEEP instrument obtains in-situmeasurements of particle size distribution,optical transmission, and the opticalvolume scattering function (VSF). Using ared 670nm diode laser and a customsilicon detector, small-angle scatteringfrom suspended particles is sensed at 32specific log-spaced angle ranges. Thismeasurement is post-processed to obtainsediment size distribution, volumeconcentration, optical transmission, andVSF. The electronics and opticalconfiguration in the LISST-DEEP are verysimilar to Sequoia’s workhorse, the LISST-100X. However, because of the extremedifficulty associated with keepingalignment under high pressure, the LISSTDEEPhardware design is radically differentfrom the LISST-100X. This allows theLISST-DEEP to be deployed down to 3000m and obtain reliable measurements ofthe in situ particle size distribution andvolume concentration in waters withoptical transmission up to 98.5%.
