WELCOME

It is our pleasure to welcome you to MULCOPIM’14. From the first edition in 1993, the International Workshop on Multipactor, Corona and Passive Intermodulation has become a reference meeting forum for researches, designers, test engineers and users of any space high power RF hardware. The intention is to share valuable in-formation on the design and testing of high power RF hardware for the prevention of RF breakdown (Multipactor and Corona) and Passive Intermodulation.

This year, and for the third time, MULCOPIM has been organised in Valencia (Spain). We hope you will enjoy this 8th edition of MULCOPIM as well as the city of Valencia and its wonderful Mediterranean landscapes.

We would like to thank all the people who have contributed with their work in this MULCOPIM edition, espe-cially those who have participated in the technical and organizing committee. We dedicate a special mention to the institutions that have contributed by sponsoring MULCOPIM’14: Generalitat Valenciana, Val Space Consor-tium, Orbital, Times Microwave Systems, Keysight Technologies, Aurora Software and Testing, Dare Development, Rohde&Schwarz, Distron, CST, Alava Ingenieros and FULTON. We would like to conclude our welcome message by expressing our thanks to the Technical University of Valencia and the University of Valencia for the availability of their facilities and their sponsorship.

If you wish to use a SPARK3D trial version for a 6 week period, please contact us:

SPARK3D is a unique simulation tool capable to determine the Breakdown power level in a wide variety of passive devices. By importing the Electromagnetic field from some of the most well-known EM commercial solvers, SPARK3D is able to analyse vacuum breakdown (multipactor) and gas discharge (corona). As outcome, the maximum power that the device can handle without developing a discharge is provided.

Thanks to its coupling to commercial tools, it is highly flexible and versatile allowing the analysis of any type of component based on a wide range of technologies such as cavities, waveguides, microstrip, antenna, etc. Moreover SPARK3D can be easily extended to be used by other software tools.

SPARK3D is a module of FEST3D (www.fest3d.com) that can be also acquired as an stand-alone program.

The Standard in EMC Instruments & Software, Consultancy and Training

Nulling Card for the effective detection of impedance changes

Compact, robust, flexible and integrated Solution

The best available solution for the detection of multipactor events. The operation of the nulling card is based on adding two signals of equal amplitude and opposite phase, resulting in a 100% cancellation of the signal. For any small change in amplitude and/or phase, the cancellation is reduced. The appearance of a signal effectively indicates a change in impedance. The two input signals of the nulling plug-in card are derived from forward and reflected power measurements by means of a dual directional coupler.

Integrated Solution DARE!! Instruments offers an ultra-compact and operator friendly solution for test campaigns where nulling detection is needed to observe High Power RF effects in DUT’s. In classic set-ups the nulling detection is achieved with a number of variable attenuators, phase shifters, combiners and interconnecting cables. These are now all be replaced by one single RadiCentre® fitted with the NUL1001A plug-in card, providing a direct output to the observing measurement instrument (spectrum analyser or receiver).

Full Control To offer a large degree of flexibility to the operator, the NUL1001A plug-in card can control amplitude AND phase in both branches. When one of the branches is reaching the limit of its control span, the nulling can be regained by changing the setting in the other branch.

Smart User Interface A conventional nulling system, set-up from separate components, does not provide any indication with regard to the direction the operator has to perform any adjustment. In contrary the NUL1001A equipped RadiCentre® provides a user interface with the following information and indicators:

• Control range of attenuator and phase shifters • Programmed test frequency • Power bars (RFL and FWD) at the display indicate internal power

balance at the summing point • A nulling bar showing the direction of the nulling optimum, without

the need to monitor the Spectrum Analyzer or Receiver

Control Interface To control attenuator and phase shifter, up and down buttons are available on the RadiCentre® color touch screen. An alternative control is obtained with the Human Interface Device (HID1001A) four dial interface. By connecting the HID to the RadiCentre® each of the four rotary dials is assigned to one of the parameters. The rotation speed of the dials adjusts the step speed, thus efficiently obtaining target values.

Everything Micro: Microwave, Microsize and Microconsumption The R&S®SMB100A signal generator family extended to 20/40 GHzRight from the first glance, these signal generators are remarkable. Compact? Absolutely. Light? Without a doubt. And they even cover the frequency spectrum from RF to microwave and offer unprecedented cost-efficiency, without compromising on signal strength or quality.

❙ Wide frequency range from 100 kHz to 20/40 GHz❙ Outstanding signal quality with excellent single side band phase noise, even at very low frequencies❙ High output power of up to +27 dBm❙ Low operating costs due to low power consumption❙ Compact size (2 HU, 3/4 19”, 6.9 kg)

The low cost of ownership as well as fast level and frequency switching make these signal generators the perfect choice for users in every field. In addition, due to their compact size and low weight, they are ideal for mobile use.
