A New Model to Determine Passive Intermodulation Terms When Non-Contributing Carriers are Added to Classical Scenarios

Smacchia, Davide; Soto Pacheco, Pablo; Boria Esbert, Vicente Enrique; Raboso García-Baquero, David (Institute of Electrical and Electronics Engineers, 2021)

[EN] This paper provides a new theoretical model for the characterization of passive intermodulation behaviour when non-contributing carriers (i.e., carriers which do not directly affect the particular non-linear contribution ...
A New Reference Sample for High-Frequency Multipactor Testing

González-Santatecla, Pablo; Smacchia, Davide; Alcaide-Guillén, Carlos; Soto Pacheco, Pablo; Rodríguez Pérez, Ana María; Morro, J. V.; Mata-Sanz, Rafael; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers, 2023-06)

[EN] Multipactor (MP) is a high-power effect severely limiting the performance of satellite communication links. A reference sample is normally used in the experimental setups for MP testing in order to verify its correct ...
A Wideband Diplexer for Ka-Band Passive Intermodulation Measurement

Smacchia, D.; Carceller, C.; Guglielmi, M.; Soto Pacheco, Pablo; Boria Esbert, Vicente Enrique; Ruiz, J.; González-Santatecla, Pablo (IEEE, 2018-06-15)

In this paper we propose a novel Ka-band waveguide diplexer for passive intermodulation (PIM) measurements. Due to the higher operating frequency, this type of measurement setup usually requires wideband filters. In ...
Advanced Techniques for the Characterization and Experimental Validation of Passive Inter-Modulation Effect (PIM) in Space Communications Systems

Smacchia, Davide (Universitat Politècnica de València, 2022-04-26)

[ES] Los satélites de telecomunicación operan en entornos multiportadora, bajo una demanda continua de mayores capacidades de transmisión. Esto ha originado un aumento en los niveles de potencia de RF, frecuencias de ...
Implementation of Waveguide Terminations With Low-Passive Intermodulation for Conducted Test Beds in Backward Configuration

Smacchia, Davide; Soto Pacheco, Pablo; Guglielmi, Marco; Morro, J. V.; Boria Esbert, Vicente Enrique; Raboso, David (Institute of Electrical and Electronics Engineers, 2019-10)

[EN] This letter proposes a simple procedure to implement low-passive intermodulation (PIM) terminations in waveguide technology to measure conducted backward PIM. The procedure consists in inserting a filter before the ...
Remote Reconfiguration of Microwave Filters Using Dielectric Tuners

Sharma, Abhishek; Ossorio, Javier; Smacchia, Davide; Tronser, Tillman; Cogollos, Santiago; Boria Esbert, Vicente Enrique; Guglielmi, Marco (Institute of Electrical and Electronics Engineers, 2023-07)

[EN] The objective of this article is to explore the use of dielectrics to reconfigure remotely microwave filters in rectangular waveguide. To start, we study experimentally the phase shift that is achievable using dielectric ...
