MFC 18925

MFC 18925 Dual-Passband C-Band Bandstop Filter | 3.4–4.2 & 4.5–4.8 GHz
The MFC 18925 is a dual-passband C-band bandstop filter engineered to protect 3.4–4.2 GHz and 4.5–4.8 GHz satellite receive bands from adjacent-band interference. With 20 dB min and up to 30 dB typ rejection between 4.25–4.40 GHz, it is ideal for blocking terrestrial signals between satellite allocations. It integrates easily with other C-band bandpass filters, such as model 13962, to create a composite system that suppresses out-of-band energy below 3.625 GHz, between 4.2–4.5 GHz, and above 4.8 GHz. Designed for professional SATCOM environments, it features a low 0.2 dB typ insertion loss and standard CPR229F flanges.
