It provides information and rules for the preparation of detail specifications for series TMA r.f. connectors together with the pro forma blank detail specification. Series TMA connectors have a characteristic impedance of 50 ω and are normally used with r.f. cables or microstrip in microwave fields that has a blind entry and middle low power. The connectors can be used up to a frequency of at least 6 GHz. It also prescribes mating face dimensions for general purpose connectors, dimensional details of standard test connectors grade 0, gauging information and tests selected from IEC 61169-1 applicable to all detail specifications relating to series TMA connectors.
