HSINCHU, TAIWAN– April 9, 2025 – Microelectronics Technology Inc. (MTI), a leader in advanced communications technologies, is pleased to announce the successful design, development, and initial mass production delivery of its LEO Ka-Band outdoor transceivers for use with Telesat’s (Nasdaq and TSX: TSAT) revolutionary Telesat Lightspeed Low Earth Orbit (LEO) satellite network. These advanced transceiver components are designed for use in Telesat User Terminal (UT) solutions, incorporating a Block Upconverter (BUC) and Low Noise Block downconverter (LNB).

The LEO Ka-Band transceivers, developed by MTI, are engineered to meet the rigorous performance demands of LEO satellite communication. Designed to provide high-throughput, low-latency connectivity, the transceivers are optimized for use in challenging environments such as maritime fleets and enterprise sectors, ensuring reliable and robust satellite communication worldwide.

“The MTI transceivers are an integral part of our UT ecosystem enabling access to the Telesat Lightspeed network,” stated Aneesh Dalvi, Telesat’s Vice President of Lightspeed Systems Development. “Our collaboration and partnership with MTI have been outstanding, and we’re looking forward to deploying this solution globally.”

The transceiver design and development were rigorously tested and qualified by Telesat, ensuring that they meet the network’s stringent performance standards. MTI has delivered the first batch of these advanced transceivers to Telesat, marking a significant milestone in the ongoing collaboration between the two companies. MTI plans to produce the transceivers in its mass production facility following final integration and validation with Telesat reference UT.

Telesat Lightspeed is an enterprise-class LEO satellite network that will deliver secure, reliable and flexible low-latency connectivity to users worldwide. The constellation, initially consisting of 198 advanced satellites, is designed for seamless global coverage with optical inter-satellite links and high-performance data processing in space. As a key enabler for global communications, this network will support both electronically and mechanically steered antennas, offering tailored connectivity solutions for a variety of customer needs.

“We are proud of the success we’ve achieved and the role MTI has played in supporting Telesat’s vision for the Telesat Lightspeed UT ecosystem,” said Eugene Wu, CEO of MTI. “This partnership underscores our expertise in developing and manufacturing high-performance communications technologies that meet the unique demands of the satellite communications industry. We look forward to continuing our collaboration with Telesat to drive innovation and expand access to reliable, high-speed satellite services around the world.”

With the successful qualification and delivery of these components, both MTI and Telesat are poised to continue driving innovation and furthering the deployment of next-generation satellite communications.
