Precision Ka‑Band WR‑28 Waveguide Components – Custom Built for Your Applicatio
As a specialist manufacturer of Ka‑band WR‑28 (26.5–40 GHz) waveguide components, we machine each part strictly to customer drawings. Unlike higher millimeter‑wave bands, WR‑28 offers a balanced combination of moderate tolerances (typically ±5 μm to ±10 μm) and robust power handling, making it ideal for satellite equipment, communication links, phased‑array radar, and automotive radar – markets where reliability and repeatability matter as much as electrical performance.
We are a trusted manufacturer of iris filter waveguide WR28, producing iris filters with window tolerances of ±5 μm to lock center frequency precisely. Our horn arrays are machined with flare angle and aperture tolerances of ±10 μm, delivering stable gain and controlled sidelobes. For couplers (directional and cross), we hold coupling hole positions within ±10 μm, ensuring directivity ≥20 dB. Choke flanges are cut with groove depth and width tolerances of ±5 μm for reliable high‑frequency sealing, while circulators feature Y‑junction cavity symmetry ≤5 μm to achieve isolation >20 dB across the full band.
As a dependable supplier of WR28 components, we deliver electromechanical switches with rotor‑stator gaps ≤10 μm – critical for low insertion loss and high isolation in redundant satellite systems. Terminations are manufactured with absorber cavity tolerances of ±10 μm, holding VSWR ≤1.03:1. We produce twists with polarization rotation accuracy of ±0.5°, multiplexers with cavity dimension consistency of ±5 μm, and combiners, dividers, and isolators that meet strict amplitude balance (±0.5 dB) and phase consistency (±5°) requirements.
Our typical materials include aluminum (with gold or silver plating) for lightweight radar applications, as well as oxygen‑free copper for high‑power satellite links. We inspect every component using CMM and VNA up to 40 GHz. Send us your drawings – we will deliver WR‑28 waveguides machined exactly to your satellite, communication, radar, and automotive specifications.
