The 2503A1 is a bead-supported Type N coaxial air line used as a calibration standard for vector network analyzer measurements, with an electrical length of 29.979 cm and an odd 1/4-wavelength frequency of 0.83 GHz. It operates from DC to 3.0 GHz with a maximum VSWR of 1.03. The center conductor is supported by dielectric beads for automatic alignment, enabling easy connection. The part is designed for low-loss, high-accuracy reference applications.
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.
