MFC 13961W-3665/4165

13961W-3665/4165 C-Band Bandpass Filter | 3665–4165 MHz | Extreme Out-of-Band Rejection

The 13961W-3665/4165 C-band bandpass filter is engineered for high-rejection performance across the 3665–4165 MHz range. Featuring ultra-low insertion loss (~0.5 dB) and up to 80 dB rejection from 5.8–7.25 GHz, it ensures strong suppression of 5G, WiMAX, and other out-of-band signals. With compact CPR-229G/F flanges and low group delay variation, it’s ideal for professional satellite receive systems requiring high linearity and signal clarity.
