Minsk Research Institute of Radiomaterials of the National Academy of Sciences of Belarus offers consumers gallium arsenide (GaAs) wafers under a manufacturing agreement.
OJSC "Minsk Research Institute of Radiomaterials" of the National Academy of Sciences of Belarus manufactures gallium arsenide wafers designed to convert an optical signal into an electrical signal at a speed of up to 2.5 Gbit/s ( TU RB 100428401.088-200).

Gallium arsenide wafers have certain advantages over silicon ones:
* high electrical resistivity, as well as a high value of the dielectric constant;
* can operate at higher power levels because they have higher breakdown voltages;
* have a high mobility and saturation rate for electrons;
* provide reliable isolation between different devices;
* generate less noise when operating at high frequencies;
* less susceptible to temperature changes.

Additional comments
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.
