MFC 7893D

7893D C-Band Bandpass Filter | 3700–4200 MHz | 70 dB Rejection

The 7893D C-band bandpass filter is built for reliable interference suppression in satellite downlink systems. With a 3700–4200 MHz passband and up to 70 dB rejection at 3500 and 4400 MHz, it effectively blocks 5G, WiMAX, and radar signals outside the C-band. This low-loss, compact filter features CPR-229 flanges, minimal group delay, and high return loss—making it ideal for VSAT and commercial ground station deployments.
