MFC 20158

SMW 20158 C-Band Bandpass Filter | 3800–4200 MHz | 60 dB Rejection, Low Loss

The SMW 20158 C-band bandpass filter is built for satellite downlink systems needing strong out-of-band interference rejection. With a 3800–4200 MHz passband, it provides up to 60 dB rejection from 3400–3600 MHz and at 4500 MHz, while maintaining low insertion loss under 0.5 dB. Its compact design, excellent VSWR, and group delay control make it ideal for 5G and terrestrial noise suppression in outdoor SATCOM applications.
