Norsat International Inc.
Norsat MEDIBX175DS-XT-C MEDIAN 175W X-Band GaAs BUC (DC + INT Ref High Stability)
For the X-Band Median BUC, a receive reject filter must be purchased as an add-on accessory unless:
1) you are using a Tx-only antenna and do not require the receive function; or
2) your terminal already includes embedded filters. The receive reject filter is sold separately at an additional cost.
The Standard Version MEDIAN BUCs offer higher gain to reduce the need for line amplifiers in long cable runs (IFL). In contrast, the WGS-Compatible Versions have lower gain to allow operation with IF signals driven up to 0 dBm.
Cyber-Hardened Intelligent BUCs are designed to enhance satellite ground terminal security for industries requiring optimized and flexible protection. These BUCs implement effective security management controls—including encrypted authentication, privacy, and access control—to ensure end-to-end message transmission. They help protect against session hijacking, password attacks, and eavesdropping.
