Waveguide flanges are critical for connecting RF/microwave systems, with four primary types dominating 90% of industrial use: ​​UPC flanges​​ (WR-90 standard, 8.2–12.4 GHz, 0.1dB insertion loss) are universal for lab equipment; ​​CPR flanges​​ feature choke grooves for military radars, achieving -80dB leakage; ​​cover flanges​​ enable quick testing with precision 2µm surface finishes; and ​​square flanges​​ […]

A waveguide dummy load absorbs RF/microwave energy (e.g., 1–40 GHz) to test transmitters safely, preventing signal reflection. Typical models handle 50W–50kW power with VSWR <1.1. Used in radar calibration (e.g., 90% of military systems) and 5G base station testing, featuring water-cooled designs for sustained 30-minute 100% duty cycles.
