Designed for seamless signal transitions between rectangular waveguide systems and standard coaxial transmission lines, our comprehensive lineup of Waveguide-to-Coaxial Adapters delivers exceptional electrical performance, ultra-low VSWR, and superior phase stability. Covering a broad frequency spectrum from 8.2 GHz to 110 GHz, our adapters span standard rectangular waveguide sizes from WR-90 down to sub-millimeter WR-10.
Whether you are designing X-band radar systems, Ku/Ka-band satellite communication earth stations, 5G/6G mmWave test benches, or high-frequency scientific instrumentation, our adapters provide reliable, low-loss transitions. Available in end-launch and right-angle configurations, with precision coaxial interfaces such as SMA, N-Type, 3.5mm, 2.92mm (K-Type), 2.4mm, and 1.85mm (V-Type), each unit is manufactured from high-grade aluminum or oxygen-free copper (OFC) with corrosion-resistant finishes.
What is the difference between an end-launch and a right-angle waveguide-to-coaxial adapter? An end-launch adapter extends straight out in line with the waveguide axis, which is ideal when space allows linear routing. A right-angle adapter places the coaxial connector perpendicular to the waveguide broad wall, saving valuable vertical space in crowded test setups or enclosure designs.
How do I select the right coaxial connector for high-frequency bands like WR-10? For mmWave bands above 40 GHz (such as WR-28, WR-15, and WR-10), standard SMA or N connectors cannot propagate those frequencies without cutting off or creating high-order modes. You must use precision coaxial connectors like 2.92mm (K-type) up to 40 GHz, 2.4mm up to 50 GHz, or 1.85mm / 1.0mm for W-band (WR-10) up to 110 GHz.
Do you support custom flange configurations or custom frequency ranges? Yes! We offer customized mechanical configurations, special flange pairings (e.g., UG to CPR adapters), and custom surface platings to meet your exact project requirements.
