Minsk Research Institute of Radiomaterials of the National Academy of Sciences of Belarus offers consumers monolithic digital attenuators «MDA 1113» under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

OJSC "Minsk Research Institute of Radiomaterials" of the National Academy of Sciences of Belarus manufactures monolithic digital attenuators «MDA 1113» designed for use as part of ultra-wideband transmitting and receiving microwave modules.

Attenuators are made of monolithic technology on the structures of gallium arsenide. The active element of the attenuator is a field-effect transistor with a Schottky gate, the length of which is 0,5µm.

Attenuators have the following distinctive features:
* integral execution;
* microstrip construction;
* wide frequency range;
* wide temperature range.

Attenuators are characterized by:
* minimum values of reverse reflection;
* stable degree of signal attenuation;
* long-term use;
* high level of reliability;
* compact dimensions;
* ease of use.

The specialization of the institute includes the following main areas:
* development and production of the element base and functional units of microwave technology (solid-state microwave monolithic integrated circuits - low-noise amplifiers and power amplifiers, protective devices, switches, attenuators, frequency converters; microwave modules, etc.);
* development and production of optoelectronic components and modules based on them (photodetectors, light emitting diodes, semiconductor lasers, receiving and transmitting optical modules);
* production of materials for semiconductor production - gallium arsenide substrates of the "epi-ready" standard;
* development of sensor technology, modules and systems (sensors for inclination, pressure, acceleration, electronic compass, etc.);
* development and production of medical equipment.

The research and production base of the institute includes dedicated equipment which allows to develop and perform a full cycle of technological operations for the manufacture of microwaves, optoelectronic components, sensors of physical quantities based on microelectromechanical systems, equipment for the manufacture of medical products - Glucosen sensors etc. In particular, the equipment allows cutting semiconductor ingots of A3B5 compounds (GaAs, InP, GaN, etc.), grinding and polishing wafers, epitaxial growth, thermal diffusion and implantation of dopants, microcircuit packaging, control of their parameters, etc.

The Institute has a licensed software for electrodynamic calculations, its own library of standard elements, methods for monitoring and testing microwave components in the C, S, L, X, K wavelength ranges, electronic lithography equipment with a resolution of 100 nm, which provides a modern level of design standards.

As part of the specialization, the development of technologies, components and devices for various radio-electronic systems is carried out: radar systems, fiber-optic communication lines, laser rangefinders, systems for leveling and orientation of objects, control systems, guidance and navigation, etc.
