Dolph Microwave

What Dolph Microwave does

Dolph Microwave is a privately held Chinese manufacturer, founded in 2001 and headquartered at FengHuiNan Road NO.34 in the Xi'an High-Tech Zone, that designs and produces precision waveguide components, earth station antennas, and RF/microwave sub-assemblies. The product portfolio spans double-ridged and standard waveguide components (loads, terminations, circulators, isolators, tees, bends, twists, transitions, adapters, couplers, switches, rotary joints, calibration kits), SATCOM antennas from quick-deploy flyaway units to 11.3-meter earth stations plus LEO/MEO/HEO/GEO tracking antennas, complete antenna feed networks (feedhorns, OMTs, diplexers, polarizers), industrial microwave hardware at 915 MHz and 2450 MHz with power handling up to 20 kW CW, and bespoke RF/microwave systems for government, military, and defense — including SIGINT applications. Technical coverage is unusually broad: waveguide sizes from WR10 to WR2300+, frequencies from 0.32 GHz to 112 GHz, VSWR as low as 1.05:1 on flanges and 1.2:1 on adapters, insertion loss from 0.2 dB, and space-quality low-outgassing options for vacuum environments down to 10⁻⁹ Torr.

The company operates a project-based B2B direct sales model: products are configured and quoted against customer specifications rather than sold through catalog e-commerce, with custom RF system work requiring direct engineering engagement from requirement definition through verification and delivery. Manufacturing is in-house — CNC machining, waveguide forming and bending, plating, soldering, brazing, anodising, grinding, electroforming — and finished products are verified in a hybrid anechoic chamber for EMC pre-compliance. The business holds ISO 9001:2015 certification scoped to waveguide component design, manufacture and sale, plus RoHS-compliant products. Customers are vertical-segmented across Defense and Government, Satellite Communications, Telecommunications, Industrial and Scientific Research, and Medical Equipment, with primary strategic emphasis on defense and SATCOM. Revenue streams are hardware product sales, custom RF system integration engineering services, and precision calibration kit sales. The company reports no disclosed funding history, no named customers, no parent company, no subsidiaries, and no management team in the input data; the disclosed headcount is 5, suggesting a small, founder-led manufacturing operation.
