MFC 21000A-3700/4200

21000A-3700/4200 C-Band Bandpass Filter | 3700–4200 MHz | 5G Rejection
The 21000A-3700/4200 bandpass filter is engineered for satellite downlinks requiring tight guard band protection. It offers strong adjacent-band rejection—up to 60 dB at 4210 MHz—while preserving signal quality with low insertion loss and excellent return loss. Ideal for blocking 5G and terrestrial interference in professional C-band systems.
