Ruselectronics holding has developed a range of radiation-resistant microwave switches for modern space platforms. New fully domestically produced devices will be able to replace similar products that are made by French, German and US manufacturers and used on communication satellites.

A spacecraft includes up to 20 microwave signal amplifiers and transmitting-and-receiving equipment. All equipment is interconnected by means of microwave paths that include microwave switches to provide system redundancy and signal transmission with minimum loss. The new radiation-resistant product range includes R type waveguide microwave switches, C type and T type coaxial microwave switches. 

“The waveguide switches are designed for integration into modern satellite communication, navigation, telecommunication platforms and repeaters. These devices are used for microwave signal switching between three channels. Coaxial microwave switches are also designed for operation on modern spacecraft. Moreover, these types of devices are widely used in ground-based systems such as antennas, measuring instruments and performance monitoring units,” said Rostec’s representatives. 

The new products are fully domestically made — beginning from materials used in the parts to electronic components. In particular, the microwave switches use actuators made by Special Design Bureau of Relay Equipment.
