MFC 17748

17748 C-Band Multi-Purpose Filter | 3.4–4.2 GHz | High Rejection, Low Loss

The MFC Model 17748 is a versatile C-Band receive filter offering exceptional rejection across multiple interference bands while maintaining minimal insertion loss within the 3.4–4.2 GHz satellite downlink range. Ideal for dense RF environments, it not only blocks standard 5.825–6.725 GHz transmit band signals, but also mitigates interference from maritime navigation, point-to-multipoint wireless, and X-band sources. With 50–80 dB stopband rejection and 0.45 dB typ. loss, it’s a reliable solution for professional SATCOM installations.
