1.1 Scope. This specification covers the performance requirements and tests for between series
and within series, radio frequency (RF), coaxial connector adapters.
1.2 Classification. Adapters consist of the following classes with the Part Identifying Number (PIN),
as specified (see 3.1).
a. Class 1 A class 1 adapter is an adapter 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 adapter is intended to provide mechanical connection within an RF circuit
providing specified RF performance.
1.2.1 PIN. The PIN consists of the letter "M" followed by the basic specification sheet number. The
first digit in the dash number designates the material and finish of the adapter body (shell); i.e., "0" for
silver plated brass, "3" for passivated corrosion-resistant steel, "4" for gold plated copper beryllium, "6"
to be used between series SMA and other series (SMA body to be corrosion resistant steel and the
other series to be brass), or "7" for nickel plated brass. Succeeding digits will be assigned to
designate the former `UG' number or a nonsignificant number, as applicable.
