AO Microwave is a manufacturer of millimeter-wave waveguide components, RF passive components, antennas, and coaxial cable assemblies, headquartered in Xi'an, China, serving customers across North America and Europe.

The waveguide portfolio covers standard WR bands from WR-2300 to WR-10 (0.32 to 110 GHz): waveguide-to-coaxial adapters, low-VSWR waveguide loads and terminations, DPDT latching waveguide switches, crossguide directional couplers, ferrite circulators, and waveguide limiters, all available with custom flange types and band configurations.

Coaxial components include fixed attenuators, RF terminations rated from 2 W to 1500 W, and precision connectors and adapters in SMA, N, 7/16 DIN, TNC, BNC, 3.5mm, 2.92 mm, 2.4 mm, 1.85 mm, and 1.0 mm interfaces. Antennas include standard-gain horn and double-ridged horn models for antenna measurement, EMC testing, and RF chamber work.

Cable assemblies span nine product series for different system demands: the CA Series ultra-low-loss, amplitude- and phase-stable flexible cable for precision measurement, the CC Series test-grade cable covering DC to 110 GHz, CSF semi-flexible cable for dense phased-array routing, and CE, CF, and CK semi-rigid series for VNA, phased-array, and airborne payload interconnects.

AO Microwave supplies both standard and custom-engineered solutions to system integrators, OEMs, test and measurement laboratories, brand owners, and distributors. Typical applications include telecom, 5G, satellite communications, aerospace, defense, radar, EMC, and medical equipment. Engineering support is provided from design through production, with most standard enquiries quoted within 24 hours and no minimum order quantity on catalog parts.

Full product specifications, datasheets, and application notes are available at www.aomicrowave.com — or contact us directly with your frequency band, power level, and interface requirements for a technical recommendation.
