IMST GmbH has demonstrated a prototype of a new multichannel RF transceiver integrated circuit designed to support next-generation satellite communications, Earth observation, and navigation payloads. The prototype was showcased in the Microwave Laboratory at the European Space Agency's (ESA) European Space Research and Technology Centre (ESTEC), highlighting its potential for software-defined satellite architectures and digital beamforming applications.
The highly integrated transceiver combines both transmit and receive functions within a single chip, enabling the direct conversion of wideband radio-frequency signals into digital data and vice versa. By integrating multiple RF functions into a compact device, the chip is designed to simplify satellite payload architectures while reducing hardware complexity and power consumption.
Designed for Reconfigurable Satellite Systems
According to IMST, the transceiver supports a wide range of operating frequencies, providing a high degree of programmability and in-orbit reconfigurability. The flexible architecture enables satellite designers to adapt system functionality to evolving mission requirements while reducing the number of discrete RF components required within the payload.
“Our transceiver supports a wide range of radio frequencies, allowing for a high degree of programmability and reconfigurability on the go,” comments Jan Steinkamp, radio frequency engineer at IMST. “By integrating multiple capabilities onto a single chip, we simplify a system's hardware complexity while significantly reducing its power consumption at the same time.”
“IMST's new highly integrated circuit represents another critical European intellectual property (IP) block developed in one of Europe’s deep-submicron semiconductor technology nodes,” adds Václav Valenta, ESA’s microwave engineer. “It is suitable for a wide range of applications, including software-defined radios and digital beamforming – strategic technologies at the heart of modern satellite constellations.”
