ADAPTERS, CONNECTORS, COAXIAL, RADIO FREQUENCY, (BETWEEN SERIES AND WITHIN SERIES), GENERAL SPECIFICATION FOR
|Publication Date:||20 July 1982|
This specification covers between series and within series, radio frequency (rf), coaxial connector adapters (see 6.1).
Adapters shall be of the following classes, as specified (see 3.1):
Class 1 - Characteristics are completely defined to provide superior rf performance. Class 2 - Characteristics are appropriately defined to provide required rf performance.
The military part number shall consist of the letter 'M' followed by the specification sheet number, and a five-digit dash number (see 3.1).
NOTE: The first digit in the dash number will be assigned to designate the material of the adapter body; i.e., '0' for brass; '1' for phosphor bronze; '2' for aluminum; '3' for corrosion-resisting steel; '4' for copper-beryllium; '5' to be used between series SMA and other series. SMA body to be copper beryllium and the rest of the adapter to be brass; '6' to be used between series SMA and other series. SMA body to be corrosion resistance steel and other series body to be brass; succeeding digits will be assigned to designate the former 'UG' number or a nonsignificant number, as applicable (see 3.1).
The connectors covered by this specification are intended for use in rf applications up to the frequency
