Gallium Phosphide IMPATT Sources for Millimeter-Wave Applications
The potentiality of millimter-wave (mm-wave) double-drift region (DDR) impact avalanche transit time (IMPATT) diodes based on a wide bandgap (WBG) semiconductor material, Gallium Phosphide (GaP) has been explored in this paper. A non-sinusoidal voltage excited (NSVE) large-signal simulation method has been used to study the DC and high frequency characteristics of DDR GaP IMPATTs dsigned to ope...
متن کاملDiagnostic Measurements for Power Transformers
With the increasing age of the primary equipment of the electrical grids there exists also an increasing need to know its internal condition. For this purpose, offand online diagnostic methods and systems for power transformers have been developed in recent years. Online monitoring is used continuously during operation and offers possibilities to record the relevant stresses which can affect th...
متن کاملMillimeter-Wave GaN HEMT for Power Amplifier Applications
Gallium nitride high electron mobility transistors (GaN HEMTs) were developed for millimeter-wave high power amplifier applications. The device with a gate length of 80 nm and an InAlN barrier layer exhibited high drain current of more than 1.2 A/mm and high breakdown voltage of 73V. A cut-off frequency fT of 113GHz and maximum oscillation frequency fmax of 230GHz were achieved. The output powe...
متن کاملMultiple Batch Sizing through Batch Size Smoothing
Batch sizing in different planning period is categorized as a classical problem in production planning, that so many exact & heuristic methods have been proposed to solve this problem, each of which considering various aspects of the original problem. The solution obtained from majority – e.g. MRP – is in this format that there may be some periods of idleness or each period should produce a...
متن کاملPiezoelectric Transformers for Space Applications
Piezoelectric transformers (PTs) have been successfully applied as step-up transformers for backlighting Cold Cathode Fluorescent Lamp s (CCFL) used in the liquid crystal displays of notebook computers. In the last decade, the interest in PTs has evolved to a second group of applications. Worldwide companies are now investigating the use of PTs for power applications, including battery chargers...
