Radio-frequency connectors - Part 52: Sectional specification for series MMCX RF coaxial connectors

IEC 61169-52:2015(E), which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for RF coaxial connectors with snap-on coupling, typically for use in 50 Ohms cable networks (MMCX). It prescribes mating face dimensions for general purpose connectors grade 2, 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 MMCX RF connectors. This specification indicates recommended performance characteristics to be considered when writing a detail specification and it covers test schedules and inspection requirements for assessment levels M and H. The MMCX miniature snap-on coupling structure series R.F. coaxial connector with the characteristic of normative impedance 50 Ohms are used with various kinds of R.F cables and strips. The operating frequency limit is up to 6 GHz.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 61169-52 has been prepared by subcommittee 46F: R.F. and

microwave passive components, of IEC technical committee 46: Cables, wires, waveguides,

R.F. connectors, R.F. and microwave passive components and accessories

1 Scope

This part of IEC 61169, which is a sectional specification (SS), provides information and rules

for the preparation of detail specifications (DS) for RF coaxial connectors with snap-on

coupling, typically for use in 50 Ω cable networks (MMCX).

It prescribes mating face dimensions for general purpose connectors – grade 2, 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 MMCX RF connectors.

This specification indicates recommended performance characteristics to be considered when

writing a detail specification and it covers test schedules and inspection requirements for

assessment levels M and H.

The MMCX miniature snap-on coupling structure series R.F. coaxial connector with the

characteristic of normative impedance 50 Ω are used with various kinds of R.F cables and

strips. The operating frequency limit is up to 6 GHz.

NOTE Metric dimension are original dimensions. All undimensioned pictorial configurations are for reference

purpose only.

The diameter chosen shall meet the characteristic impedance of (50 ± 0,5) Ω.

Design for slotting is optional, and should meet electrical and mechanical requirements, when mating with

Φ0,39 mm~Φ0,41 mm gauge pin.

4 Quality assessment procedure
4.1 General

Clause 10 of IEC 61169-1:2013 applies to this sectional specification, except the following

requirement:

Subclauses 4.2 to 4.4 provide recommended rating, performance and test conditions to be

considered when writing a detail specification. They also provide an appropriate schedule of

tests with minimum levels of conformance inspection sampling. Together with the pro forma

blank detail specification (BDS) and instructions for the preparation of a detail specification.

4.2 Rating and characteristics (see Clause 5 of IEC 61169-1:2013)

The values indicated below are recommended for MMCX series RF coaxial connectors and

are given for the writer of the detail specification. They are applicable for the condition when

the connectors are fully mated.

Certain tests are listed without any recommended values being given. These tests will usually

not be required. When these tests are required, appropriate values shall be entered in the

detail specification at the discretion of the specification writer.

Preferred climatic categories are given in Table 7. Rating and characteristics are given in

Table 8.
