Satellite signal amplification in ultra-high frequency bands
RESHETNEV company (under ROSCOSMOS State Corporation umbrella) has updated the technology of manufacturing low noise amplifier (LNA) – the device with a special onboard mission.
At ultra-high frequencies, the satellite is able to work with increased amounts of information, but the interference impact in such bands is more noticeable. Due to that, it is more difficult for on-board receivers to detect and process the radio signal received by the antenna. A low-noise amplifier comes to their aid. It is designed in such a way that its own noise during operation is negligible. The radio signal is amplified with minimal distortion. This increases the satellite capabilities when performing its mission – communications, navigation, and so on – in the interests of service consumers.
In the early 2000s, RESHETNEV company has launched independent LNA manufacturing. The LNAs were used in GLONASS, LOUTCH, GONETS and EXPRESS satellite systems. Today, the company's specialists have modified the device based on circuit and design solutions that meet modern requirements. The LNAs are based solely on Russian element base, materials and technologies.
LNA The device went through a full cycle of ground-based experimental testing. Autonomous tests and inspections at the irradiation system level have confirmed its ability to successfully carry out its mission on board. The new generation low noise amplifier is planned to be employed in RESHETNEV company satellites for various purposes.
