The 12 GHz maximum frequency is unusually high for a 75 Ohm BNC, putting this connector in the premium tier for high-bandwidth serial digital video links. ## Cable Compatibility — Canare L-5.5CUHD and Beyond The factory-specified cable is Canare L-5.5CUHD, a precision 75 Ohm broadcast coax with a 5.5 mm outer diameter. This connector is not listed as compatible with RG59 or Belden 1505F — those are different cable constructions with different dielectric diameters and impedance characteristics. Using this plug on an unspecified cable will shift the impedance and degrade the return loss at higher frequencies. For a BOM match, confirm the cable type before committing the line item.","metaTitle":"Amphenol RF 031-70552-12G BNC Plug, 75 Ohm, 12 GHz","metaDescription":"Amphenol RF 031-70552-12G BNC plug, 75 Ohm, 12 GHz max frequency.
