26、ICAL COMMISSION _ PASSIVE RF AND MICROWAVE DEVICES, INTERMODULATION LEVEL MEASUREMENT Part 1: General requirements and measuring methods FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees
27、 (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 Repo
28、rts, 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 n
29、on- 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
30、 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 ar
31、e 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 inte
32、rnational 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
33、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 use
34、rs 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 oth
35、er 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.
36、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 paten
37、t rights. International Standard IEC 62037-1 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, published in 2012-05. This fir
38、st edition of IEC 62037-1 replaces IEC 62037, published in 1999. It constitutes a technical revision. The text of this standard is based on the following documents: FDIS Report on voting 46/402/FDIS 46/416/RVD 4 62037-1 IEC:2012 Full information on the voting for the approval of this standard can be
39、 found in the report on voting indicated in the above table. The French version of this 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 RF
40、 and microwave devices intermodulation level measurement, can be found on the IEC website. 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 pu
41、blication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its content
42、s. Users should therefore print this document using a colour printer. 62037-1 IEC:2012 5 PASSIVE RF AND MICROWAVE DEVICES, INTERMODULATION LEVEL MEASUREMENT Part 1: General requirements and measuring methods 1 Scope This part of IEC 62037 deals with the general requirements and measuring methods for
43、 intermodulation (IM) level measurement of passive RF and microwave components, which can be caused by the presence of two or more transmitting signals. The test procedures given in this standard give the general requirements and measurement methods required to characterize the level of unwanted IM
44、signals using two transmitting signals. The standards in this series address the measurement of PIM, but do not cover the long term reliability of a product with reference to its performance. This standard is to be used in conjunction with other appropriate part(s) of IEC 62037. 2 Normative referenc
45、es None. 3 Abbreviations CATV Community antenna television DUT Device under test IM Intermodulation PIM Passive intermodulation 4 Characteristics of intermodulation products PIM interference is caused by sources of non-linearity of mostly unknown nature, location and behaviour. A few examples are in
46、ter-metallic contacts, choice of materials, corrosion products, dirt, etc. Most of these effects are subject to changes over time due to mechanical stress, temperature changes, variations in material characteristics (cold flow, etc.) and climatic changes, etc. The generation of intermodulation produ
47、cts originates from point-sources inside a DUT and propagate equally in all available directions. The generation of passive intermodulation products (PIM) does not necessarily follow the law of the usual non-linear equation of quadratic form. Therefore, accurate calculation to other power levels cau
48、sing the intermodulation is not possible and PIM comparisons should be made at the same power level. Furthermore, PIM generation can be frequency-dependent. When PIM generation is frequency- dependant, the PIM performance shall be investigated over the specified frequency band. 6 62037-1 IEC:2012 5
49、Principle of test procedure Test signals of frequencies f 1 and f 2 with equal specified test port power levels are combined and fed to the DUT. The test signals should contain at least 10 dB less harmonic or self- intermodulation signal level than the expected level generated in the DUT. The PIM is measured over the specified frequency range. The intermodulation products of order (2f 1 f 2 ), (2f 2 f 1 ) etc.
