Italian SME delivering rad-hard ASIC design and electric propulsion expertise for European space research consortia.
Microtest SRL is an Italian engineering SME based in Vicopisano that operates in the space technology sector, contributing specialist technical expertise to European research consortia. Their work covers two distinct but complementary space engineering domains: radiation-hardened (rad-hard) ASIC design using advanced semiconductor processes, and high-power electric space propulsion systems. In EFESOS, they worked on evaluating 22nm FD-SOI process technology for space-grade integrated circuits, covering analog converters, PLLs, and high-speed serial interfaces designed to survive radiation environments. In ASPIRE, they pivoted to advanced electric propulsion, contributing to Hall Effect Thruster development with a focus on high-thrust, high-Isp direct-drive architectures.
EFESOS project focused on 22nm FD-SOI process evaluation for space-grade ASICs, including rad-hard design platforms, design kits, and analog/digital interfaces such as ADCs, DACs, PLLs, and high-speed serial links.
ASPIRE project involved Hall Effect Thruster technology including monolithic and cluster approaches, direct-drive architecture, and high-thrust/high-Isp configurations targeting 20 kW power levels.
Company name and involvement in EFESOS — evaluating a semiconductor process for space suitability — strongly implies hardware testing and qualification capability, though this is inferred rather than explicitly stated in project keywords.
Microtest's first H2020 project (EFESOS, 2019) was firmly rooted in microelectronics — specifically the evaluation of 22nm fully-depleted silicon-on-insulator semiconductor technology for rad-hard ASICs used in space, including the development of design kits and IP libraries for converters and serial interfaces. By 2021, their second project (ASPIRE) had moved into an entirely different subsystem domain: high-power electric space propulsion, with keywords around Hall Effect Thrusters, direct-drive architecture, and cluster configurations. This is a significant technical breadth for a two-person-equivalent SME and may reflect either broad space engineering service capabilities (design, test, integration) or a deliberate strategy to expand from electronics into propulsion subsystems.
Microtest appears to be broadening its space engineering portfolio from semiconductor-level electronics into propulsion subsystems, positioning itself as a multi-domain space technology SME — a trajectory that could make them a versatile contributor to future ESA and EU space program consortia.
Microtest has participated exclusively as a consortium partner, never as a coordinator, indicating they join projects to deliver specific technical outputs rather than to manage or lead programs. With 10 unique partners across 2 projects, their network is compact and targeted — consistent with a specialist SME that is sought out for niche expertise rather than one that drives consortium formation. There is no evidence of repeat partnerships, suggesting their collaborations are opportunity-driven rather than anchored in long-term relationships with a fixed group of partners.
Microtest has worked with 10 unique partners across 7 countries over 2 projects, giving them a genuinely European but relatively thin network. Their collaboration footprint is modest and consistent with an SME that participates selectively in technically specialized projects.
Microtest occupies an unusual niche for an Italian SME: they have demonstrable experience in both radiation-hardened microelectronics (a field dominated by large space primes and specialized semiconductor firms) and advanced electric propulsion (a fast-growing area for in-space transportation). Few organizations of this size can claim involvement in both the electronic brain and the propulsion engine of a spacecraft. For consortium builders assembling teams for ESA or Horizon Europe space calls, Microtest offers deep technical specialization and the agility of an SME without the cost structure of a large contractor.
