GB/T 11322.1-2013Radio frequency cables -- Part 0: Guide to the design of detail specifications -- Section 1: Coaxial cables (English PDF)

Foreword

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 11322.1-1997 "RF cables - Part 0. Guide to the design specification details a coaxial cable".

This section compared with the GB/T 11322.1-1997 main technical changes are as follows.

--- Increased half air and foam FEP PE material values \u200b\u200b(see Table 4);

--- Increasing the nominal outside diameter of 9.00mm medium as a preferred value (see Table 11);

--- Recommended media outer diameter D2 is preferably a value of 0.87mm, 1.50mm, 2.95mm, 3.70mm, 4.80mm, 7.25 mm, 9.00mm, 11.50mm, 17.30mm (see 4.2);

--- Increasing the characteristic impedance of different media types and media and the outside diameter of the tolerance value (see Table 13);

--- Increasing the outer diameter of the medium is preferably solid PE values \u200b\u200bin 9.00mm and 11.50mm; foamed PE increased medium outer diameter of the preferred value 2.95mm, 3.70mm, 9.00mm, 11.50mm and 17.30mm (see Table 13).

This section uses redrafted law revision adopted IEC 60096-0-1:2000 "radio frequency cables - Part 0. Detail Specification Design Guide the first one coaxial cable. " this part of IEC 60096-0-1:2000 technical differences are as follows.

--- Increasing the nominal outside diameter of 9.00mm medium as a preferred value (see Table 11);

--- Added "nominal outside diameter D2 of the medium is preferably 0.87mm, 1.50mm, 2.95mm, 3.70mm, 4.80mm, 7.25mm, 9.00mm, 11.50mm, 17.30mm "(see 4.2);

--- Solid PE media to the outer diameter of the nominal value, increased 9.00mm and 11.50mm, tolerance of 0.40mm to 17.30mm 0.30mm; foam PE media Nominal outer diameter increased 2.95mm, 3.70mm, 9.00mm, 11.50mm and 17.30mm (see Table 13);

--- Increase the formula F = 10D2 D1 (N) (see Table 24).

To IEC 60096-0-1:2000 errors were the following modifications.

--- 5.2 D1e = D3exp (-Z0 epsilon2/60) to D1e = D3exp (-Z0 epsilon2/60;

--- Figure 1 k4 (W/m2K1) to k4 (W/m2K1.25);
