Kiva Dzhurinsky Foreign miniature low-pass filters. Key to information about filters
Developers of radio-electronic equipment in the microwave range are increasingly using imported low-pass filters to suppress electromagnetic interference in power circuits and pulse signals [1], which allows the development to be carried out more reliably and more quickly. But for this it is necessary to understand and be able to analyze foreign information about filters: catalogs, advertising sheets, a more detailed description of a specific type of filter (data sheet) in order to correctly select the necessary filters. The journal "Components and Technologies" published a similar material about foreign radio frequency connectors [2]. This article is intended to help consumers and distributors navigate foreign information about miniature low-pass filters used in electronic equipment.

Nathan Feldman Pass-through microwave chambers and their use in installations for electromagnetic processing of materials
Waveguide microwave chambers are considered that implement various processes of material processing in a microwave electromagnetic field, when the material passes through a series of chambers in a continuous flow, crossing each of them in a plane parallel to the narrow wall of the waveguide. The relative position of the passage slots in the waveguide, their length, width, as well as methods of protecting the entrance and exit of the chamber from parasitic electromagnetic radiation are determined. Methods for measuring the current dielectric characteristics of the material are analyzed.

Yuri Sankin, Boris Ivanov, Mikhail Dvoesherstov, Sergey Simakov, Valery Utkin, Igor Kulaga Russian HF and microwave resistors, absorbers and terminators. State and prospects of production
The development of microwave electronics in the last decade has acquired colossal proportions. This is, first of all, the emergence of radio and telecommunication means of communication and navigation for civilian use, for example, the well-known systems of GSM, GPRS, GPS, GLONASS and others. Digital processing and information transmission systems are already operating at ultrahigh frequencies, modern processors - in the microwave range. The development of radar of all types of basing is progressing at a rapid pace. The automotive industry is introducing active safety systems based on microwave radar. Microwave measuring technology is developing in parallel. All of these areas are the scope of application of RF and microwave resistors, terminators (matching loads) and absorbers (attenuators). The article discusses the types of RF and microwave passive electronic components produced in Russia, as well as highlights the problems and prospects for the development of their production.

Yuri Proskuryakov Distributed energy metering systems
Cars with hybrid engines and technologies to reduce fuel consumption, energy-saving lighting lamps and LEDs, solar panels, the use of renewable energy sources, smart home systems aimed at reducing energy consumption, microcircuits with ultra-low power consumption, household appliances have already firmly entered our life. class "A". These and other trends of modern reality are permanently and irreversibly changing the world towards global energy conservation. In order to save money, one must not only understand how we can do this, but also qualitatively assess all items of expenditure - here and below we will talk about energy metering systems and the advantages of their implementation.

Artem Kozlov SuperH Renesas microprocessors in modules for multimedia applications
The availability of low-cost embedded computing modules based on powerful and highly integrated 32-bit processors can significantly change the capabilities of new industrial equipment. For example, such inexpensive modules can help provide a high-quality graphical interface that will become even more accessible to the user as the price of color displays come down. In addition, thanks to processor support for audio and video applications, we are beginning to find completely new areas of application for them.

Thomas Kugelstadt Design principles with capacitive digital isolators
Constantly changing safety requirements in the operation and development of electronic equipment make it necessary to use galvanic isolators in almost all systems for collecting and transmitting data. One method of isolating low-voltage circuits in the control system from potentially hazardous voltages in the sensor and drive sections on site is to use digital isolators. This article describes the basic functions of capacitive digital isolators to facilitate the design of isolated systems, explains their placement in the signal path, and offers important guidelines for successful PCB design.

Mark Cantrell, translation: Nikolay Isakov Digital Isolator Simplifies USB Galvanic Isolation in Medical and Industrial Applications
The personal computer (PC), which is today the de facto standard for transferring information at home and in the office, communicates with most peripheral devices via a universal serial bus (USB). The standardization, price, and availability of software have made the PC platform attractive as a host processor for medical and industrial applications, but the security and reliability requirements imposed in these growing markets are very different from the office and home applications for which the platform was designed. ...

Vincent Chuffart VPX: The technology of the future for today's applications
Today, modular serial switching structures with very high EMI immunity and signal integrity are in high demand, even in extremely harsh applications. VITA (VMEbus International Trade Association) has developed corresponding baseline and sub-specifications for extremely reliable sequential switching structures for VPX systems (VITA 46 series). The main document is already an ANSI standard (ANSI/VITA 46.0-1997). This means that this specification, while providing a very high degree of EMC and signal integrity, is promising. The new COTS embedded device standard is expected to be useful not only for current, but also for future users of VME applications.
