Description (English):

IEC 63138-2:2023, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for MQ4 series circular connectors with four RF channels, as well as a detailed specification of the blank format. An MQ4 series circular connector with 50 Ω nominal impedance has four RF channels which can 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 connector provides two coupling mechanisms, a quick-lock and a threaded coupling. MQ4 series circular connectors can be used in mobile communication systems and in other communication equipment. This document also specifies the mating face dimensions and gauging information of MQ4 series circular connectors, and tests selected from IEC 63138-1, applicable to all detail specifications relating to MQ4 series circular connectors.

Abstract

Overview

IEC 63138-2:2023 is the sectional specification (SS) for MQ4 series circular connectors, published by the International Electrotechnical Commission (IEC). It complements IEC 63138-1 by providing the information and rules needed to prepare detail specifications (DS) for four‑channel, 50 Ω multi‑channel RF connectors. The document covers mating face dimensions, gauging information, a blank DS pro forma, quality assessment procedures and a selection of tests from IEC 63138-1 applicable to all MQ4 detail specifications.

Key topics and technical requirements

Connector family: MQ4 series circular connectors with four RF channels that can be engaged/disengaged simultaneously.
Impedance: 50 Ω nominal for RF channels.
Mechanical variants:
- Plug connectors: two plug versions - quick‑lock and threaded.
- Socket connector: supports both quick‑lock and threaded coupling.
Mating face dimensions and gauging:
- Detailed drawings and dimensional tables for plug, socket and individual RF channel mating faces.
- Gauge designs and dimensional tolerances to verify mechanical compatibility and interchangeability.
Testing and quality:
- Selection of applicable tests from IEC 63138-1, including mechanical compatibility and return loss inspections.
- Quality assessment procedures: rating and characteristics tables, inspection procedures (lot‑by‑lot, periodic and qualification).
Detail specification (DS) guidance:
- Instructions and a blank DS pro forma to help manufacturers and standards writers produce consistent product specifications.
- Marking, ordering information and packaging requirements.

Practical applications and users

IEC 63138-2:2023 is intended for engineers and organizations involved in the design, manufacture, testing and procurement of RF connectors:

Connector designers and manufacturers-use the standard to develop compliant MQ4 part families and to prepare product detail specifications.
Test laboratories and quality‑assurance teams-use gauging and test selection guidance to verify mechanical compatibility, electrical performance and lot conformity.
OEMs and system integrators-ensure mechanical and RF interoperability in mobile communication systems and other communication equipment.
Procurement and compliance officers-reference the standard for supplier requirements and acceptance criteria.
