Overview

EN 61169-59:2017 (CLC adoption of IEC 61169-59:2017) is a sectional specification for threaded multi‑pin radio‑frequency connectors type L32-4 and L32-5. It gives the rules and information required to prepare detail specifications (DS) for 50 Ω multi‑pin RF connectors with an anti‑mismating mechanism and an operating frequency per channel up to 4 GHz. The document includes mating‑face dimensions (general connectors - grade 2), gauging details, and selected tests from IEC 61169‑1, plus a pro‑forma blank detail specification and recommended performance characteristics.

Key topics and technical requirements

• Connector types covered: L32‑4 (4 pin) and L32‑5 (5 pin), with pin and socket variants and threaded coupling.
• Electrical characteristics: Nominal impedance 50 Ω, RF channel operating frequency up to 4 GHz.
• Mechanical & dimensional data: Mating face dimensions for general connectors (grade 2) and complete gauging information to ensure interchangeability and anti‑mismating function.
• Quality and conformity: Quality assessment procedures, rating and characteristics tables, and guidance on qualification approval and maintenance.
• Testing and inspection: Test schedules and inspection requirements for assessment levels M (manufacturer) and H (higher/harsher), including acceptance and periodic tests drawn from IEC 61169‑1. Annex A provides an isolation test method.
• Detail specification guidance: Instructions for preparing DS documents, including selection of tests, performance limits, marking, and ordering information. The specification contains a blank DS pro‑forma to standardize procurement and manufacturing documents.

Practical applications

• Widely used in mobile communication base stations and subsystems - cited examples include TD‑SCDMA and TD‑LTE systems.
• Suitable for multi‑channel RF interconnects where compact, threaded, multi‑pin connections with anti‑mismating capability and controlled 50 Ω performance are required.
• Useful in test equipment, telecom RF modules, and other equipment requiring reliable multi‑channel RF interfaces up to 4 GHz.

Who should use this standard

• Connector manufacturers and designers creating Detail Specifications (DS) for L32‑4/L32‑5 products.
• Quality and compliance engineers developing conformance and test plans.
• Procurement and specification engineers in telecom and RF system integrators who need standardized connector requirements.
• Test labs performing acceptance and periodic testing against IEC/EN requirements.

Related standards

• IEC 61169‑1 - Generic specification for RF connectors (requirements and measuring methods)
• IEC 61726 - Screening attenuation measurement (reverberation chamber)
• IEC 62037 series - Intermodulation level measurement for passive RF/microwave devices

Using EN 61169‑59:2017 ensures consistent mechanical, electrical and quality requirements for L32‑4 / L32‑5 radio‑frequency connectors, facilitating interchangeability, reliable RF performance (50 Ω, ≤4 GHz) and standardized procurement/testing practices.

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.
