The 2553T3.12 is a beadless coaxial air line, type N, designed for use as a precision calibration standard in microwave measurement applications. It has an electrical length of 3.123 cm, with an accuracy of ±0.01 cm, and is rated for frequencies up to 18 GHz with a VSWR of less than 1.004 plus 0.001 times the frequency in GHz. The center conductor is unsupported and floats freely within the air dielectric body, and the male connector nut is retractable to ease center conductor contact alignment before tightening.
Coaxial air lines are air-dielectric transmission lines with highly accurate dimensions that can be used as fundamental impedance standards in measurement and calibration applications, and may also be used to establish reference positions for measurements.
Bead supported air lines offer greater convenience and easier connections (the center conductor is automatically aligned by the dielectric bead for easy connection); beadless air lines offer better impedance and electrical length accuracies, as well as lower VSWR (the center conductor floats free in the air line body, and the male connector nut is retractable to facilitate insertion of the center conductor contact before the thread- on connection tightened.
