MFC 19759

MFC 19759 C-Band Receive Filter | Multi-Band Interference Rejection

The MFC Model 19759 is a high-performance C-band receive filter designed to block out a broad range of RF interference beyond just the standard transmit reject band. It covers a 3.4–4.2 GHz passband with ultra-low insertion loss and rejects unwanted signals from 3.25 GHz to 14 GHz, including maritime navigation, radar, and wireless services. Its compact design, CPR229G/CPR229F flanges, and no-power installation make it ideal for high-density SATCOM systems.

Key Features:

Passband: 3.4–4.2 GHz

Insertion Loss: ≤0.3 dB @ Fo, ≤0.5 dB at edges

Return Loss: ≥20 dB

Stopband Rejection:
   75 dB min @ 3.25 GHz and 4.35–14.0 GHz
   24 dB typ. @ 3.35 & 4.25 GHz
