MFC 21000C-3700/4200

21000C-3700/4200 C-Band Bandpass Filter | IP67 Rated, 60 dB Rejection

The 21000C-3700/4200 is a rugged C-band bandpass filter designed for outdoor satellite receive systems operating in the 3700–4200 MHz range. With up to 60 dB rejection below 3670 MHz and 30 dB above 4230 MHz, it effectively suppresses out-of-band interference while maintaining excellent in-band performance. Housed in an IP67-rated enclosure, it offers low insertion loss and stable group delay—ideal for professional SATCOM environments requiring 5G mitigation.
