Mechanical Characteristics
Using these mechanical dimensions, you can calculate the expected electrical performance with the
equations in the following publications:
•
Nelson, Robert E., and Marlene R. Coryell, "Electrical Parameters of Precision, Coaxial, Air-Dielectric
Transmission Lines", U.S.National Bureau of Standards Monograph No. 96.
•
Somlo, P.L., “The Computation of Coaxial Line Step Capacitances”, IEEE Transactions on Microwave
Theory and Techniques, Volume MTT-15, No. 1, January, 1967.
The measurement method in these publications provides a general idea of the expected device
characteristic impedance. Variations in connector interfaces can have a large effect on your actual electrical
measurements.
Airline Mechanical Characteristics
The dimensions of the airline outer conductor are shown in
. This outer conductor is common to
both airlines. Two conductors are provided with the kit.
The dimensions of the 50
airline and the 25
mismatch airline are shown in
CAUTION
The center and outer conductors of the airlines in this kit have been mechanically measured
and matched. Do
not
use the center or outer conductors provided in this kit with a center or
outer conductor from any other airline. Damage to the airline or attaching connector may
result.

a. The relationship between the length of the inner conductor and the length of the
outer conductor determines the airline center conductor recession. Refer to
b. In this case, the center conductor is 0.0001 inch (0.0025 mm) longer than the outer
conductor.
