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.
