MFC 21000A-3700/4200

The 21000A-3700/4200 C-band bandpass filter is engineered for precise rejection of close-in interference while maintaining excellent in-band performance. With a 3700–4200 MHz passband, it delivers up to 60 dB rejection at 4210 MHz and 55 dB below 3700 MHz, effectively mitigating adjacent 5G and terrestrial signals. Its solid mechanical design, low insertion loss, and moderate group delay make it ideal for fixed satellite downlink installations where tight guard band protection is required.
