MFC 12086-1

12086-1 C-Band Transmit Reject Filter | 3.7–4.2 GHz | 50 dB Rejection

The 12086-1 is a high-performance SATCOM transmit reject filter covering 3.7–4.2 GHz. Engineered for installation between the antenna and LNA, it provides 50 dB typical rejection in the 5.925–6.425 GHz transmit band while maintaining an ultra-low insertion loss of just 0.06 dB. This compact WR-229 waveguide filter is ideal for C-band earth stations and transceivers that demand high isolation and low receive loss.
