Satcom Filters and Diplexers

Knowles Dielectric Labs Satcom filters address the growing demand for low-SWaP (size, weight, and power) devices in the rapidly evolving satellite market. These planar microstrip filters, printed on temperature-stable ceramics, offer a high-performance alternative to bulky waveguide and lossy MMIC filters. Designed for demanding environments, these filters support critical frequency control and interference management in both space and ground segments. The range of offerings includes filters and diplexers that cover the standard Ku and Ka satcom operating bands of next-generation satellite systems and ground terminals.
