Челябинская компания «ПЛАНАР» известна специалистам в области СВЧ-электроники не только в нашей стране. Работая на этом рынке уже более 30 лет, предприятие постоянно развивает свои технологии, результатом чего стал успех «ПЛАНАРА» как производителя одних из самых сложных контрольно-измерительных приборов – векторных анализаторов цепей, которые компания поставляла в том числе на мировой рынок.

О том, как удалось компании достичь этого успеха, как она конкурировала с крупнейшими мировыми производителями контрольно-измерительного оборудования, как повлияли на ее деятельность изменения на рынке, произошедшие в прошлом году, а также о других направлениях деятельности предприятия и его планах на будущее мы поговорили с директором ООО «ПЛАНАР» Сергеем Александровичем Заостровных.

The article shows a methodological approach to assessing and selecting a manufacturer of microwave components from China for possible use in radioelectronic equipment. The approach is based on a generalization of practical work experience and reflects those main and characteristic points that a development engineer usually takes into account. Keywords: microwave components, business model, Chinese manufacturer, organizational and economic criteria, technical criteria, fabless company.

A three-gap multibeam prismatic klystron resonator with planar strip elements on a dielectric substrate was studied. The results are obtained, which confirm that the resonator can be used in low-voltage transient multibeam amplifying or generator klystrons.

The article discusses the main structural materials used for electromagnetic shielding, such as gaskets, contact springs, fabrics, heat shrink tubes, RF radiation absorbers. A technique for confirming the characteristics of shielding materials in TESTPRIBOR JSC EMC laboratory is described.

The article provides information on K10-90 surface mounted multilayer ceramic capacitor series produced by Kulon LCC. It describes a number of features of the company’s production facility upgrading which allowed 1005M (0402) capacitors production in series.

The article reviews highly reliable connectors from Quanwei, which are used in all critical industries: aviation, unmanned systems, data transmission, navigation, industrial automation, transport, energy, etc. The official representative of Quanwei is Promtekhkomplekt JSC.

An analysis of the architecture of the virtual hardware prototype was carried out to identify problematic components with a view to their subsequent refinement. It is noted that in the early stages this approach simplifies software development in the future.

The article presents the technology for creating software blanks for test and verification equipment even before not only this equipment, but also the product for which it is intended is manufactured. This approach makes it possible to reduce the overall order lead time (product plus test equipment), optimize the requirements for test equipment resources and telemetry acquisition modes, and avoid some time-consuming and sometimes uncorrectable development errors.

The article investigates two systems of PCB activation-sensitization before the stage of direct metallization: activation with graphite and activation with copper hypophosphite based complex. A comparative analysis of these methods with the SYSTEM-S palladium activator, one of the most developed direct metallization technologies today, was carried out.
