AO Microwave has introduced a line of waveguide-to-coaxial adapters for system integrators bridging waveguide and coaxial RF architectures. The adapters cover standard WR bands including WR-28, WR-42, WR-75, and WR-90, with precision-machined flanges designed for low VSWR and minimal return loss. They support radar, satcom, 5G backhaul, and RF test setups where reliable transitions between waveguide and coaxial sections are critical. Custom interface combinations and frequency ranges are available for OEM and defense programs. Datasheets and interface drawings are posted at https://www.aomicrowave.com/products/waveguide-to-coaxial-adapter?utm_source=mwrf&utm_medium=pr&utm_content=wg_coax_adapters
