Radio-frequency connectors - Part 59: Sectional specification for type L32-4 and L32-5 threaded muti-pin radio-frequency connectors (IEC 61169-59:2017)

This part of IEC 61169, which is a sectional specification (SS), provides information and rules
for the preparation of detail specifications (DS) for type L32-4 and L32-5 threaded multi-pin
radio frequency connectors with anti mismating mechanism, 50 Ω nominal impedance. The
operating frequency of each channel is up to 4 GHz. These connectors have been widely used
in mobile communication system like TD-SCDMA and TD-LTE, and can also be used in some
similar equipment.
It also prescribes mating face dimensions for general connectors-grade 2, gauging information
and tests selected from IEC 61169-1, applicable to all detail specifications relating to type
L32-4 and L32-5 multi-pin connectors.
This sectional specification provides information and rules for the preparation of detail
specifications for type L32-4 and L32-5 multi-pin connectors together with the pro forma blank
detail specification.
This specification indicates the 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.
NOTE Metric dimension are original dimensions.
All undimensioned pictorial configurations are for reference purpose only.

RADIO-FREQUENCY CONNECTORS –

Part 59: Sectional specification for type L32-4 and L32-5
threaded multi-pin radio-frequency connectors

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 61169-59 has been prepared by subcommittee 46F: RF and
microwave passive components, of IEC technical committee 46: Cables, wires, waveguides,
RF connectors, RF and microwave passive components and accessories.
The text of this International Standard is based on the following documents:

Material: steel, polished. Surface roughness: Ra ≤0,4 μm.

Test procedure:
a) Sizing test
The gauge A should insert the socket centre contact of RF channel three times; this is a
sizing operation.
b) Insertion test
Following the sizing operation, if specified in the detail specification, the force necessary
to insert Gauge B fully into the socket centre contact shall be measured. When this test is
required, the insertion force shall not exceed 8,9 N.
c) Retention test
After sizing or insertion test, the gauge C shall be inserted into the socket centre contact.
The contact shall retain the mass of the gauge C in a vertical downward position.
