Passive RF and microwave devices, intermodulation level measurement - Part 3: Measurement of passive intermodulation in coaxial connectors

IEC 62037-3:2012 is part of the IEC 62037 series, and defines the impact test on coaxial connectors to evaluate their robustness against weak connections and particles inside the connector as independently as possible from the effects of cable PIM (passive intermodulation).

Dispositifs RF et à micro-ondes passifs, mesure du niveau d'intermodulation - Partie 3: Mesure de l'intermodulation passive dans les connecteurs coaxiaux

La CEI 62037-3:2012 définit l'essai de choc sur des connecteurs coaxiaux pour évaluer leur robustesse dans le cas de connexions faibles et contre des particules à l'intérieur des connecteurs, aussi indépendamment que possible des effets de l'intermodulation passive des câbles. Pour les autres connecteurs (par exemple les connecteurs montés sur panneaux), le câble peut être remplacé par une ligne de transmission adéquate (par exemple guide d'ondes, ligne à ruban). Afin d'évaluer les effets des contraintes mécaniques sur les connecteurs, une série de chocs est appliquée aux connecteurs, tout en mesurant l'intermodulation passive.

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.

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 connector 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 connectors, a series of impacts is applied to the connectors while

measuring the PIM.
2 Normative references

a) Setup 1 – Multi-port DUT

In order to minimize the effect of the transmission line, a short assembly should be tested.

Identical connectors should be assembled to each end. An assembly, as short 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 Connection 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 frequency 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, 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 frequenc
