Precision-Crafted Submillimeterwave & Terahertz Components – Made to Your Drawings

As a dedicated manufacturer of submillimeterwave antennas and RF devices, we specialize exclusively in precision machining. Our portfolio covers pyramidal horn , sectoral horn, conical horn, corrugated horn antennas, slot array, and leaky-wave antennas, as well as mixers and resonators including waveguide filters and other RF devices. We also supply submillimeterwave connections and interfaces – waveguide flanges, covers, dowel pins, gaskets, seals, and adapters.

What sets us apart is our commitment to custom manufacturing. Every project begins with your drawing. Whether you need a non‑standard horn profile, a bespoke flange pattern, or a unique filter cavity, we machine each component directly from your CAD or blueprint. No re‑interpretation, no compromises – just exact geometry, tight tolerances, and superior surface finish.

We do not cast, mould, or assemble from off‑the‑shelf parts. Instead, we rely on advanced CNC milling and turning, micro‑machining, and EDM processes to achieve the fine details required for submillimeterwave performance. From prototypes to production runs, each piece is inspected to ensure it meets your specified dimensions and material requirements.

When your application demands precise beam shaping, low‑loss transmission, or reliable interfacing at millimeter and submillimeter wavelengths, trust the precision machinist. Send us your drawing – we will deliver the hardware, exactly as you designed.
