Measure a waveguide flange against its approved interface drawing, not the WR designation alone. Verify the aperture, mounting holes, alignment features and mating face using tools capable of resolving the specified tolerances. Record the datum system, temperature, measurement results and uncertainty. A waveguide designation identifies the guide size. It does not uniquely define the flange […]

To test waveguide connector performance, measure ​​insertion loss​​ (should be <0.1 dB for Ka-band) and ​​VSWR​​ (target <1.25:1) using a vector network analyzer. Conduct ​​durability tests​​ (500+ mating cycles) while monitoring ​​contact resistance​​ (must stay below 5mΩ). Verify ​​EMI shielding​​ effectiveness (>90dB attenuation at 40GHz) and ​​thermal stability​​ (-55°C to +125°C operating range). For millimeter-wave
