Microwave capacitors manufactured by EKB TEST
Microwave capacitors play a vital role in the development of high-frequency technologies. They are used in radar systems, communications, microwave electronics, and many other fields.
Modern microwave capacitors are manufactured in surface-mount chip format, which reduces parasitic effects, while multilayer ceramic capacitors ensure high reliability.
In the Soviet Union, microwave capacitor production was organized at several enterprises specializing in the production of radio components and electronics. Among the most well-known manufacturers were:
The Voronezh Radio Components Plant (VZR) produced, for example, aluminum oxide electrolytic capacitors of the K50-9 and K50-12 series. These capacitors were used in various electronic devices, including those operating in the microwave range. The products were marked "VZR," indicating the manufacturer.
The Kation plant (Khmelnitsky, Ukraine) was one of the largest capacitor manufacturers in the USSR, including series used in microwave equipment. Its products were often used in the defense industry and were found in specialized equipment.
The Severo-Zadonsky Capacitor Plant "Electrolit" (Tula Region) also produced capacitors, including those for high-frequency and microwave applications.
The Dipol Production Association (Kamo, now Gavar, Armenia) produced capacitors of the K50-6 series, which were widely used in household and special equipment, including microwave devices.
After the collapse of the USSR and the virtual elimination of domestic electronics, most products and devices began to use foreign components, including microwave capacitors.

Until recently, one of the most common products of this class in Russia was the product of the American company American Technical Ceramics under the ATC brand.
Products from American companies Kyocera AVX, Passive Plus Inc. PPI and the Chinese company Dalicap DLC are also widely used.
Starting in 2022, deliveries of American products to Russia ceased, and the quantities imported through so-called "parallel" imports are disproportionately small to meet the needs of the domestic industry.

Chinese products are often of significantly inferior quality to American ones, and also often cause complaints about their technical support.
Company EKB TEST (St. Petersburg) develops and manufactures microwave capacitors, including analogs of leading global brands, providing a full cycle of services—from design to serial production, as well as engineering support and product testing. The products are certified for the needs of the defense industry and meet international quality standards.
The company produces ARC capacitors, which are direct replacements for ATC (American Technical Ceramics) capacitors, making them from the same materials that ATC uses.

ARC capacitors are identical to ATC capacitors in terms of their housing and parameters, but offer a number of significant advantages: prices for ARC products can be up to 20% lower than similar ATC products, there is no minimum order quantity (MOQ), measuring probes are available, delivery times are 2-3 times shorter (from 6 weeks), the products are not subject to sanctions, and developer kits are also available (a range of capacitors with 10 units of each nominal value).

The specified capacitors are intended for use in high-frequency paths of radio transmitting, communication, radar and other microwave equipment.
In addition, as part of the R&D work, EKB TEST plans to develop and mass-produce the following products:
– ultra-high-frequency multilayer ceramic chip capacitors ARC10, ARC70;
– high-frequency power ceramic chip capacitors ARC70;
– ultra-high-frequency multilayer ceramic chip capacitors with ultra-low equivalent series resistance ARC75.
The planned start date for serial production of the products is 2027. The planned production volume should be approximately 5 million units per year, with a subsequent increase to 7,5 million units per year in the period 2028-2029.
Microwave capacitors play a vital role in the development of high-frequency technologies. EKB TEST occupies a key position in Russia as a developer and manufacturer of microwave capacitors, as well as other electronic components. It provides a full cycle of services, from development and production to testing and delivery, including for the defense industry and major government customers such as ROSTEKH, ROSATOM, ROSCOSMOS, and Almaz-Antey.
EKB TEST has a certified laboratory, an implemented quality management system, and the status of a qualified supplier to the Russian Ministry of Defense. All products undergo rigorous quality control and testing according to Russian and international standards, guaranteeing their reliability and compliance with the requirements of high-tech industries.
