MFC 20541

20541 C-Band Bandpass Filter | 3820–4200 MHz with High 5G Rejection

The 20541 C-band bandpass filter is engineered to safeguard satellite downlink systems against adjacent-band and 5G interference. With a passband of 3820–4200 MHz, it delivers exceptional out-of-band rejection—up to 70 dB below 3720 MHz—while maintaining low insertion loss across the passband. Its precise group delay and excellent return loss ensure minimal signal degradation, making it ideal for professional SATCOM installations.
