Passive RF and microwave devices, intermodulation level measurement - Part 1: General requirements and measuring methods
IEC 62037-1:2025 deals with the general requirements and measuring methods for 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 document give the general requirements and measurement methods required to characterize the level of unwanted IM signals using two transmitting signals. The IEC 62037 series addresses the measurement of PIM but does not cover the long-term reliability of a product with reference to its performance. This third edition cancels and replaces the second edition published in 2021. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) added clarification that PIM generation is typically frequency dependent and noted that testing with swept or multiple fixed frequencies often provides more accurate results;
b) identified multi-port PIM analyzers as a possible test set-up topography;
c) added specification that test power level does not exceed the power handling capability of the DUT;
d) updated test specification to include missing parameters needed to properly define a PIM test;
e) added clarification that PIM test reports include the maximum PIM value measured over the test duration;
f) corrected error in Figure 3 that was erroneously changed in IEC 62037-1:2021.
Passive HF- und Mikrowellenbauteile, Messung des Intermodulationspegels - Teil 1: Allgemeine Anforderungen und Messverfahren
Dispositifs RF et à micro-ondes passifs, mesure du niveau d'intermodulation - Partie 1: Exigences générales et méthodes de mesure
L’IEC 62037-1:2025 donne les exigences générales et les méthodes de mesure du niveau d’intermodulation (IM) des composants RF et à micro-ondes passifs, qui peut être provoqué par la présence de deux ou plus de deux signaux d’émission. Les procédures d’essai présentées dans le présent document donnent les exigences générales et les méthodes de mesure exigées pour caractériser le niveau des signaux d’intermodulation indésirables à l’aide de deux signaux d’émission. La série IEC 62037 porte sur la mesure de l’intermodulation passive (PIM), mais ne couvre pas la fiabilité à long terme des produits par rapport à leurs performances. Cette troisième édition annule et remplace la deuxième édition parue en 2021. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) clarification ajoutée indiquant que la génération d'une intermodulation passive (PIM) dépend généralement de la fréquence et note indiquant que les essais à balayage de fréquences ou à des fréquences fixes multiples donnent souvent des résultats plus précis;
b) analyseurs d’intermodulation passive à plusieurs ports identifiés comme topographies de montage d'essai possibles;
c) ajout d'une spécification indiquant que le niveau de puissance de l'essai ne dépasse pas la capacité de tenue en puissance du dispositif en essai;
d) spécification d'essai mise à jour pour inclure les paramètres manquants nécessaires à la définition correcte d'un essai de génération d'intermodulation passive (PIM);
e) clarification ajoutée indiquant que les rapports d'essai de génération d'intermodulation passive (PIM) incluent la valeur PIM maximale mesurée sur toute la durée d'essai;
f) erreur corrigée à la Figure 3 qui avait été modifiée à tort dans l'IEC 62037-1:2021.

55 FOREWORD
56 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all
57 national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co -
58 operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition
59 to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly
60 Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is
61 entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in
62 this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also
63 participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO)
64 in accordance with conditions determined by agreement between the two organizations.
65 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
66 consensus of opinion on the relevant subjects since each technical committee has representation from all interested
67 IEC National Committees.
68 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
69 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
70 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation
71 by any end user.
72 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
73 transparently to the maximum extent possible in their national and regional publications. Any divergence between any
74 IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
75 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
76 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services
77 carried out by independent certification bodies.
78 6) All users should ensure that they have the latest edition of this publication.
79 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members
80 of its technical committees and IEC National Committees for any personal injury, property damage or other damage
81 of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of
82 the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
83 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
84 indispensable for the correct application of this publication.
85 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
86 rights. IEC shall not be held responsible for identifying any or all such patent rights.
87 IEC 62037-1 has been prepared by IEC technical committee 46: Cables, wires, waveguides, RF
88 connectors, RF and microwave passive components and accessories. It is an International
89 Standard.
90 This second edition cancels and replaces the first edition published in 2012. This edition constitutes
91 a technical revision.
92 This edition includes the following significant technical changes with respect to the previous edition:
93 a) clarification added that test equipment may utilize pulsed generators to reduce power
94 consumption;
95 b) heating effect differences in the device under test noted in Annex B for tests conducted using
96 pulsed generators;

97 c) guidance added in Annex B to improve probability of detection of short duration PIM events
98 while dynamic testing.
99 The text of this International Standard is based on the following documents:
