ULTRAWAVE (traveling wave tubes, DG-band) and TERAWAY (W-band, D-band terahertz links) both focus on beyond-100 GHz wireless components.
FERDINAND-BRAUN-INSTITUT GGMBH LEIBNIZ- INSTITUT FUR HOCHSTFREQUENZTECHNIK
Berlin-based Leibniz institute developing III-V semiconductor devices for high-frequency communications, GaN power electronics, and photonic applications.
Their core work
Ferdinand-Braun-Institut (FBH) is a Berlin-based Leibniz research institute specializing in high-frequency electronics, III-V semiconductor devices, and advanced photonics. They develop compound semiconductor components — particularly gallium nitride (GaN) power transistors, terahertz/millimeter-wave MMICs, and laser diodes — that serve as enabling hardware for telecommunications, power electronics, and quantum technology applications. In H2020, they contributed specialized chip-level and device-level expertise to projects spanning wireless communications beyond 100 GHz, vertical GaN power semiconductors, quantum optics, and biophotonic medical imaging.
What they specialise in
YESvGaN is their largest funded project (EUR 477K), developing vertical GaN-on-silicon power transistors — directly aligned with FBH's institutional mission.
ErBeStA explored cavity quantum electrodynamics, Rydberg blockade, and optical microresonators for error-proof Bell-state analysis.
MIB project developed endoscopic biophotonic imaging for bladder cancer diagnosis, likely contributing laser/LED source components.
ULTRAWAVE, TERAWAY, and YESvGaN all involve monolithic microwave integrated circuit or semiconductor chip design at high frequencies or high power.
How they've shifted over time
FBH's early H2020 work (2016–2018) centered on millimeter-wave wireless infrastructure — traveling wave tubes, DG-band chipsets, and network backhaul components in ULTRAWAVE, alongside an outlier contribution in medical biophotonics (MIB). From 2019 onward, their focus expanded into terahertz communications (TERAWAY), quantum photonics (ErBeStA), and especially vertical GaN power electronics (YESvGaN, their largest project). The trajectory shows a clear shift from RF communications hardware toward power semiconductors and quantum-adjacent photonics, reflecting broader European investment trends in these areas.
FBH is moving toward wide-bandgap power electronics and terahertz technology, positioning them as a key hardware partner for next-generation 6G communications and energy-efficient power conversion projects.
How they like to work
FBH participates exclusively as a partner, never as coordinator, which is consistent with their role as a specialized hardware provider contributing device-level expertise to larger system-integration consortia. With 65 unique partners across 12 countries from just 5 projects, they work in large, diverse consortia (averaging 13+ partners per project). This pattern suggests they are a trusted component-level specialist that consortia recruit for specific semiconductor or photonics capabilities rather than a project driver shaping the overall research agenda.
FBH has collaborated with 65 distinct partners across 12 countries through 5 projects, indicating broad European reach and strong demand for their specialized hardware expertise. Their network spans telecommunications, quantum research, and medical device communities.
What sets them apart
FBH occupies a rare niche as a publicly funded research institute that bridges fundamental semiconductor physics and application-ready RF/power components. Their ability to contribute across wildly different domains — from cancer diagnostics lasers to terahertz wireless chips to quantum optical devices — stems from deep mastery of III-V compound semiconductor fabrication. For consortium builders, FBH offers access to world-class cleanroom infrastructure and decades of GaN/InP device expertise that few European partners can match.
