MFC 20523

20523 C-Band Bandpass Filter | 4000–4200 MHz | High Rejection Design

The 20523 C-band bandpass filter provides robust interference rejection for satellite downlink systems operating in the 4000–4200 MHz range. With up to 70 dB stopband attenuation from 3700 to 3900 MHz, it effectively blocks out 5G and other out-of-band signals. Its low insertion loss, excellent return loss, and precise group delay performance ensure optimal signal clarity in professional SATCOM deployments.
