scope:

This specification covers the general requirements and tests for radiofrequency connectors used with flexible RF cables and certain other types of coaxial transmission lines.

Connectors shall be of the following classes, categories, and part numbers, as specified (see 3.1).

The class of connectors shall consist of the following:

a. Class 1 - A class 1 connector is a connector which is intended to provide superior RF performance at specified frequencies, and for which all RF characteristics are completely defined. b. Class 2 - A class 2 connector is intended to provide mechanical connection within an RF circuit providing specified RF performance.

The categories of connectors shall be designated by an A (field serviceable), B (non-field replaceable), C (field replaceable solder center contact), D (field replaceable crimp center contact) and E (field replaceable). as follows:

a. Category A - Connectors which do not require special tools to assemble shall be designated as category A connectors. Standard wrenches, soldering equipment, pliers, etc., are not defined as special tools. b. Category B - Connectors which require special tools to assemble shall be designated as category B connectors. These connectors may be used for original installations. Field replacement is intended to be made by category A or C connectors. Category B connectors will not be stocked or procured by the Government. c. Category C - Connectors which require only standard military crimping tools and standard cable stripping dimensions to assemble shall be designated as category C connectors. The standard military crimping tool shall be as specified (see 3.1) d. Category D - Connectors which require only standard military crimp tools for the center contact and outer ferrule, and standard cable stripping dimensions to assemble shall be designated as category D connectors. The standard military crimp tools shall be as specified (see 3.1). e. Category E - Connectors using semi-rigid cables with standard stripping dimensions and using standard military tools.

Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: US Army Communications Electronics-Command, ATTN: DRSEL - ED -TO, Fort Monmouth, NJ 07703 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

This appendix is to provide additional information to the user of this specification in performing the voltage standing wave ratio, RF leakage, and insertion loss tests.

intended Use:

Connectors and fittings covered by this specification are intended for use in radiofrequency application up to the frequency specified (see 3.1).
