New generation of telecommunication satellite payloads are becoming more and more complex, thus requiring greater data capacity together with a higher density of RF equipment on board. The input bandpass filters located in the payload receiver front-end operate over a wide band frequency range, rejecting out-of-band noise together with possible interference signals. Therefore, the main drivers for broadband input filters are compactness, wide bandwidth (BW), wide spurious frequency range, low in-band insertion loss (IL). In this scenario, the conventional filter solutions based on waveguide cavities present good performance but are bulky and heavy.

Abstract
New generation of telecommunication satellite payloads are becoming more and more complex, thus requiring greater data capacity together with a higher density of RF equipment on board. The input bandpass filters located in the payload receiver front-end operate over a wide band frequency range, rejecting out-of-band noise together with possible interference signals. Therefore, the main drivers for broadband input filters are compactness, wide bandwidth (BW), wide spurious frequency range, low in-band insertion loss (IL). In this scenario, the conventional filter solutions based on waveguide cavities present good performance but are bulky and heavy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
