Compound Semiconductor Applications (CSA) Catapult

What Compound Semiconductor Applications (CSA) Catapult does

CSA Catapult (Compound Semiconductor Applications Catapult) is a UK not-for-profit research and technology organisation established by Innovate UK in 2018 as part of the nine-centre Catapult Network, headquartered in Newport with regional hubs in Bristol (Future Telecoms Hub, opened 2023) and Glasgow (Technology & Innovation Centre). Its core mission is to accelerate UK commercialisation of compound semiconductor technologies by providing access to state-of-the-art equipment and world-leading expertise to start-ups, SMEs, large enterprises and academia. The organisation operates as a trusted neutral convener that de-risks the journey from research to market deployment across power electronics, RF and microwave communications (up to 67 GHz), photonics, advanced packaging and quantum hardware applications.

The technical portfolio is built around specialised facilities including a Power Electronics Lab with Double Pulse Testing (DPT), an RF/microwave characterisation facility covering sub-6 GHz and mmWave 5G bands, photonic integrated circuit design and validation capability, and an Advanced Packaging capability described as bespoke for wide bandgap semiconductor devices. Underpinning these are workforce programmes including the DER-IC Industrialisation Centres for power electronics upskilling, a Skills Academy offering internships and PhD sponsorships, and a UKESF scholarship scheme. Notable applied AI outcomes include a 78% design time reduction and a GaN inverter exceeding 98% efficiency, with the June 2026 rebrand to Semiconductor Catapult under the UK AI hardware plan repositioning the organisation around AI infrastructure enablement.

The revenue model is grant-funded rather than commercial: CSA Catapult is a company limited by guarantee funded primarily by Innovate UK with project-based co-funding from UKRI, the Department for Digital, Culture, Media and Sport, the Advanced Propulsion Centre, the Aerospace Technology Institute and the Centre for Connected and Autonomous Vehicles. Major funded programmes have included ESCAPE (£20m), @FutureBEV (£15m, with BMW), FABB-HVDC (£10.18m), UKTIN (£10m), GaNext (£8.7m), REACT (£5.5m), QuEOD (£3.38m) and ELIPS (£3.3m). Customers and consortium partners span blue-chip OEMs and primes (BMW, Saab, Microchip, Infineon, Siemens, BT, McLaren Applied, IQE PLC) alongside SMEs and universities, with the organisation serving over 140 companies and 928 jobs created or safeguarded since inception. Two wholly-owned subsidiaries (CSA Catapult Services Limited and Novomorphic Limited) support service delivery, and annual turnover sits below the £36m Modern Slavery Act reporting threshold.

Core offering

CSA Catapult is a not-for-profit research and technology organisation that provides start-ups, SMEs, large organisations and academia with access to state-of-the-art equipment and world-leading expertise to develop and commercialise compound semiconductor technologies. Its core offering centres on specialist testing, modelling, characterisation, integration and validation services across power electronics (including Double Pulse Testing), RF and microwave communications (up to 67 GHz), photonics, and advanced packaging, delivered through laboratories in Newport, Bristol and Glasgow and via collaborative R&D projects funded by Innovate UK and partners.

Product overview

CSA Catapult is a not-for-profit research and technology organisation funded by Innovate UK that serves as the UK's authority on compound semiconductor applications and commercialisation. Rather than a single unified product, CSA Catapult offers a portfolio of specialised technology services organised around two key market areas: Net Zero and Future Telecoms. The core service portfolio includes Power Electronics Lab Services (with Double Pulse Testing capabilities), RF & Microwave Communications testing (up to 67 GHz), Photonics Services (laser emitters to photonic integrated circuits), Advanced Packaging solutions, and the Skills Academy for workforce development. Additionally, CSA Catapult manages numerous collaborative R&D projects including the HiCap capacitor development, GaNTT gallium nitride development, GaNext (£8.7m GaN integration project), SST evaluation module, ELIPS immersion cooling systems, and quantum technology projects (QuEOD, SiNQ, QUDITS). These offerings are delivered through state-of-the-art facilities in Newport, Bristol, and Glasgow, providing access to equipment and world-leading expertise that helps start-ups, SMEs, large organisations and academia advance compound semiconductor technologies and bring products to market faster.
