Precision D- Band WR06 Waveguide Components – Made to Your Drawings
As a dedicated manufacturer of D- band WR06 (110–170 GHz) millimeter wave components, we produce high performance waveguide parts exclusively from customer drawings. Our ultra precision machining achieves micron and submicron tolerances – essential for the 1.65mm× 0.825mm inner bore of a straight waveguide, a sharp E- plane or H-plane bend, or a twist that demands ±1.5μm rotational smoothness.
We are an experienced manufacturer of iris filter waveguide WR06, where each iris filter window is held to ±1.5 μm for exact center frequency control. Our slot arrays are machined with slot length tolerances of ±2 μm to keep sidelobe levels below –25 dB, while directional couplers feature coupling hole diameter tolerances of ±2 μm, ensuring >22dB directivity. We also produce choke flanges with ring groove depth controlled to ±1 μm, and plain flanges with flatness ≤1.5 μm.
As a reliable supplier of WR06 components, we deliver switches (rotor‑stator gap 3–5 μm), terminations with smooth absorber cavities, multiplexers that maintain cavity consistency within ±1 μm, and combiners, dividers, and isolators with ferrite pocket depth tolerances of ±1.5 μm. Our circulators feature Y‑junction cavity symmetry ≤2 μm for >20 dB isolation. Additionally, we manufacture probe transitions (backshort depth ±1 μm) and power dividing networks (E‑plane T‑junctions or Magic‑Ts) with tip radii ≤0.02 mm.
Every component is machined from oxygen‑free copper (gold plated) using micro‑EDM, femtosecond laser, or 5‑axis ultra‑precision milling. We inspect each part with CMM (±0.3 μm) and VNA up to 170 GHz. Send us your drawings – we will deliver WR‑06 waveguides machined exactly to your specifications.
