24、OTECHNICAL COMMISSION _ PASSIVE RF AND MICROWAVE DEVICES, INTERMODULATION LEVEL MEASUREMENT Part 3: Measurement of passive intermodulation in coaxial connectors FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national ele
25、ctrotechnical 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 Specif
26、ications, 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. Internati
27、onal, 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
28、 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
29、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)
30、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
31、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 certific
32、ation 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
33、, 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 cit
34、ed 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 identifyi
35、ng any or all such patent rights. International Standard IEC 62037-3 has been prepared by technical committee 46: Cables, wires, waveguides, R.F. connectors, R.F. and microwave passive components and accessories. This bilingual version (2014-01) corresponds to the monolingual English version, publis
36、hed in 2012-07. The text of this standard is based on the following documents: FDIS Report on voting 46/417/FDIS 46/433/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. 4 62037-3 IEC:2012 The French version of thi
37、s standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 62037 series, published under the general title Passive r.f. and microwave devices, intermodulation level measurement can be found on the IEC we
38、bsite. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by
39、 a revised edition, or amended.

40、12 5 PASSIVE RF AND MICROWAVE DEVICES, INTERMODULATION LEVEL MEASUREMENT Part 3: Measurement of passive intermodulation in coaxial connectors 1 Scope This part of IEC 62037 defines the impact test on coaxial connectors to evaluate their robustness against weak connections and particles inside the co
41、nnector as independently as possible from the effects of cable PIM (passive intermodulation). For other connectors (e.g. panel mounted connectors), the cable can be replaced by an adequate transmission-line (e.g. airline, stripline). In order to evaluate the effects of mechanical stresses on the con
42、nectors, a series of impacts is applied to the connectors while measuring the PIM. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For und
43、ated references, the latest edition of the referenced document (including any amendments) applies.

Identical connectors should be assembled to each end. An assembly, as shor
46、t as physically practical, should be constructed. b) Setup 2 One port DUT A single connector can be assembled on a length of transmission line for which it is designed, loss or low loss, that exhibits at least 10 dB of attenuation in one direction at the lowest frequency in the receive band. 4.2 Con
47、nection of unit The unit should be connected as described in the IEC 62307-1 base document. 4.3 Setup 1 Fixed frequency test considerations Due to the phase interaction of the connectors and the length of the transmission line (configuration A) when measured in the reverse (reflected) mode, the freq
48、uency at which maximum PIM occurs within the band can vary and shall be determined. An accepted method of sweeping is to fix F1 at the low end of the transmit band and step F2 down, starting at the top of the band for all combination of frequencies that result in IM in the receive band. If desired,
49、this procedure can be reversed by fixing F1 at the highest frequency in the transmit band and then stepping F2 up, starting at the bottom of the band. If fixed frequency is used, assemblies of varying lengths shall be made to ensure that the PIM adds in-phase. Assemble 2 additional DUTs. The first one is to be /6 longer and the second one is to be /3 longer at the receive frequency of test. The PIM of t
