IEC 63138-2 pdf – Multi-channel radio-frequency connectors – Part 2: Sectional specification for MQ4 series circular connectors
1 Scope
This part of lEC 63138, which is a sectional specification(SS), provides information and rules
for the preparation of detail specifications (DS) for MQ4 series circular connectors with fourRF channels, as well as a detailed specification of the blank format.
An MQ4 series circular connector with 50 Q nominal impedance has four RF channels whichcan be engaged and disengaged at the same time.There are two versions of plug connectors,
one is a quick-lock version,and the other is a threaded version. The socket connectorprovides two coupling mechanisms, a quick-lock and a threaded coupling.
MQ4 series circular connectors can be used in mobile communication systems and in othercommunication equipment.
This document also specifies the mating face dimensions and gauging information of MQ4series circular connectors,and tests selected from IEC 63138-1,applicable to all detailspecifications relating to MQ4 series circular connectors.
