CONSTRUCTION AND USE of BROADBAND TRANSFORMERS
ثبت نشده
چکیده
Broadband transformers are not difficult to understand. They are commonplace in today's amateur technology. Most broadband transformers are wound on ferrite toroids or rods. Some are wound on powdered-iron cores, while others are formed on pot or cup cores. We will confine our discussion to transformers that are wound on ferrite toroids or balun cores (sometimes called "binocular" cores. Basic information on toroids and how to wind them is available in the Oak Hills Research application note NoT-IA. Therefore, I shall not repeat the fundamental information about toroids in this note.

A Novel Design in the Use of Planar Transformers for LDMOS Based Amplifiers in Bands II, III, DRM+, DVB-T and DAB+
The coaxial transformer-coupled push-pull circuitry has been used widely in HF and VHF amplifiers for many decades without significant changes in the topology of the transformers. Basic changes over the years concerned the construction and turns ratio of the transformers as has been imposed upon the newer technologies active devices demands. The balun transmission line transformers applied in p...
متن کاملDomain Separation by Construction
Language-based approaches to security typically use static type systems to control information flow, relying on type inference to distinguish secure programs from insecure ones. This paper advocates a novel approach to language-based security: by structuring software with monads (a form of abstract data type for effects), we are able to maintain separation of effects by construction. The thesis...
متن کاملThe Implementation of a Steam Transformer System
Steam transformers are evaporators that operate as dedicated vapour and condensate producing cells. This practice is found in the sugar refining industry and beet sugar factories, but is generally not found in raw sugar factories. Green field investments often overlook the need for such equipment, but its application can have tremendous benefits for the safe operation of the boiler. This paper ...

Managing distributed state is a di cult challenge for building scalable, distributed, wide-area applications. This project presents the design of an infrastructure, called Ivory, to simplify construction of distributed applications by automatically caching and replicating data structures and code. We illustrate the use of our infrastructure in service caches that replicate Web service code and ...
