Satellite communication (satcom) systems have undergone a revolutionary transformation in recent years. The industry has shifted from multi-billion-dollar GEO satellites to million-dollar LEO satellites, reducing costs by three orders of magnitude while exponentially increasing the number of satellites in orbit.
This evolution brings new challenges:
As satcom systems become more dynamic, interference management is critical. Both space and ground segments require advanced filtering solutions to maintain the performance and reliability of the network.
Traditional waveguide filters, while effective, are bulky and heavy—no longer suitable for modern satcom applications where size and weight constraints dominate. On the other hand, MMIC filters have high loss and temperature drift, limiting their effectiveness.
Knowles offers planar microstrip filters printed on our DLI brand temperature-stable specialty ceramics, delivering a compelling alternative:
Knowles has introduced standard products covering Ku and Ka bands, ideal for next-generation satcom systems such as VSATs, ground terminals, satellite antennas, and phased arrays.
