Filtronic has secured a $68.1 million order from SpaceX to supply its E-band gallium nitride power amplifier units. This follows a previous $62.5 million contract awarded to the company in August 2025.
Why it matters
The order highlights the growing reliance on gallium nitride semiconductors to improve power efficiency and output for low Earth orbit satellite communications. This technology is critical for scaling high-bandwidth infrastructure as satellite constellations continue to expand.
Filtronic utilizes gallium nitride (GaN) technology, a semiconductor material that enables higher output power and greater efficiency than traditional gallium arsenide solutions. This performance shift is essential for E-band satellite communication links.
The players
Filtronic
A manufacturer specializing in radio frequency and microwave electronic components for aerospace and telecommunications markets.
SpaceX
A developer of aerospace systems and operator of the Starlink satellite internet constellation.
The details
The Cerus E-band units are solid-state power amplifiers that leverage gallium nitride to handle the high frequency and power requirements of satellite links. By operating in the E-band spectrum, these units provide the high data throughput necessary for low Earth orbit satellite constellations. Gallium nitride is preferred here due to its wide bandgap, which allows the semiconductors to operate at higher voltages and temperatures with lower signal loss than older silicon or gallium arsenide alternatives.
Timeline
August 2025: Filtronic received a $62.5 million order from SpaceX.
October 27, 2026: Filtronic announced the $68.1 million order.
Fiscal Year 2028: Expected fulfillment period for the order.
The Tech Race
The transition to gallium nitride for E-band hardware marks a shift toward more capable, efficient orbital relay systems. This order places Filtronic at the center of a race to provide the high-power, miniaturized components required for next-generation satellite constellations.
The increased production of these power amplifiers supports the scaling of global low Earth orbit satellite constellations, aiming to increase bandwidth capacity. While the technology is used for backhaul infrastructure rather than consumer devices, users of high-speed satellite services may see network performance improvements as capacity expands.
The takeaway
Filtronic continues to scale its production capacity to meet the demands of commercial space infrastructure. Investors and observers should watch for delivery benchmarks during fiscal year 2028 to track the company's manufacturing throughput.
