At European Microwave Week 2025, Electronic Specifier’s Editor, Mick Elliott speaks to David Diez, Managing Director, Microwave at ERZIA about the new range of COTs amplifiers for new space applications and reveals some design enhancements.
ERZIA was founded 22 years ago and the company is based in Santander, northern Spain. ERZIA specialises in microwave and RF electronics, focusing on power amplifiers, low noise amplifiers, and integrated assemblies. Initially worked on high-reliability microwave electronics for the European Space Agency, the company has since expanded its portfolio to serve both commercial and high-end markets, including aeronautics and defence.
ERZIA currently offers over 300 products, including power amplifiers, low noise amplifiers, switches, and signal generators. Diez unveiled a new line of amplifiers tailored for new space markets, particularly addressing the growing low earth orbit (LEO) satellite sector. This line targets the gap between fully space-qualified hardware and standard commercial amplifiers.
According to Diez, customers increasingly demand units that combine reliability with strong performance without the extended development cycles or high costs associated with traditional space-grade products.
The new range, already tested with clients over the past two years, consists of 13 modules, including high-power amplifiers (HPAs) and low noise amplifiers (LNAs) across several frequency bands. For transmission, it covers commonly used KI and S bands, as well as wideband amplifiers suitable for micro-satellites and small satellite applications.
On the receiving side, LNAs cover TA, CS, C, and YB bands, enabling comprehensive support for communications, earth observation, and lunar research missions. ERZIA plans to expand the family further over the next year.
Diez spoke as to how this approach meets the needs of the rapidly growing LEO market, where missions are shorter, often three to five years, and operators are more willing to accept manageable levels of risk. This contrasts with the traditional space sector, where satellites are designed to operate for decades and undergo extensive testing and qualification. ERZIA’s products offer a balance of reliability, availability, and cost-efficiency, providing ready-to-fly solutions that reduce development time and energy budgets.
All research, development, and manufacturing take place at ERZIA’s Santander headquarters, which includes an R&D centre and production facility. The company is expanding its capabilities with a new clean room, doubling production capacity. ERZIA also has a US subsidiary for direct sales and maintains a global network of distributors, including Richardson RFPD, to support customers worldwide with technical assistance.
