MFC 19511

Model 19511 C-Band Receive Filter | Ultra-Wideband Interference Rejection

The MFC Model 19511 is a high-rejection C-band receive filter engineered to protect satellite downlinks in the 3.7–4.2 GHz range. This multi-purpose filter blocks a wide range of out-of-band signals, including C-band uplink (5.825–6.725 GHz), WiMAX, maritime navigation, and even Ku-band interference—making it ideal for high-density receive sites or spectrum-sensitive SATCOM installations. With ultra-low insertion loss and broad stopband coverage, the 19511 ensures clean signal reception in complex RF environments.
