Creation of electronic components on the basis of very high frequency payments manufacturing techniques
On July 16, 2020 it became known that specialists of Russian Space Systems holding based on manufacturing techniques of high-frequency (very high frequencies) of switching payments on organic dielectric developed the low-noise amplifier of S-range for onboard command measuring systems of spacecrafts.
According to the company, the production technology of multilayer very high frequencies payments provides formation of a thick polymeric layer in two stages due to use of combination of processes of centrifuging and spreevy drawing, shielding of electronic nodes of the printed circuit board and use of a microminiature anchor in a dielectric layer for ensuring adhesive durability of wired logic connections.
 | Due to the increase in functionality of products, increase in operating frequencies and reduction of dimensions of the monolithic integrated circuits (MIC) sharply there is a problem of creation of switching very high frequencies payments with topological regulations, comparable to MIS, and very high frequencies characteristics, necessary for production of the modern radio-electronic equipment. Andrey Buyankin, the head of department of development of onboard very high frequencies devices of AFAR RKS told |  |
| | The low-noise amplifier of S-range will become the first electronic component which is released on the basis of this technology. It will be used during creation of command measuring systems of the Russian spacecrafts. Gennady Yerokhin, the deputy CEO of RKS – the chief designer on onboard equipment told | |
The comparative estimates of characteristics of a very high frequency payments which are carried out in RKS on material Rogers4350 and organic dielectric confirmed advantage of the last regarding losses in microstrip lines and temperature range. The amplifier of S-frequency range developed by a very high frequency on a payment from organic dielectric has gain amount 4 dB better concerning the amplifier on material Rogers4350. The very high frequency a payment uses organic dielectric in the temperature range-200 … +200 °C without change of characteristics that allows to use it in an outer space. The very high frequency payment is going to be used during creation of the Russian spacecrafts.
These results are achieved in the project progress using the measures of the state support of development of cooperation of the Russian educational organizations of the higher education, the public scientific institutions and the organizations implementing complex projects on creation of technological production, provided by the order of the Government of the Russian Federation of April 9, 2010 No. 218.
The announcement of switching payments for a very high frequency devices and power amplifiers
On April 23, 2020 the Russian Space Systems company reported that it developed switching payments for a very high frequency devices and power amplifiers for production of onboard equipment of perspective satellites that will allow to increase energy efficiency of power sources of spacecrafts considerably.
According to the company, switching payments for power semiconductor devices and a very high frequency devices provide the high heat sink and density of switching that allows to reduce mass-dimensional characteristics and to increase reliability of devices.
| | The method of formation of ceramic payments developed in RKS with the end-to-end metallized openings and "deaf" openings under crystals of different value provides the special sequence of transactions of laser micro-processing, putting photoresist and etching of functional layers. As a result the labor input of production of payments decreases and specialized technology equipment is not required. Igor Smirnov, the chief of the sector of development of micromechanical systems of RKS told | |
All complex of works took 2 years. During development the group of authors managed to solve problems of formation of the bilateral drawing and openings with small ohmic resistance. As a result the switching payment differs in high heat conductivity (more than 170 W / m*k), good electric insulation properties (more than 109 Ohms), dielectric permittivity (9) and thickness of metallization of a conduction layer (up to 100 microns) and also the unit resistance of a covering of openings comparable with a unit resistance of copper.
| | We also developed technological limits on rules of design for a very high frequency - and power payments which were included into the standard of the enterprise "Microelectronic modules. Alexander Tevyashov, the leading research engineer of the sector on development of construction of micromechanical systems explained | |
