The 40W C-band BUC is a rugged, compact solid state amplifier (SSPA) with integrated block up converter (BUC) suitable for fixed and mobile satellite communications with high data rate or multicarrier requirements. The 40W C-band BUC is an outdoor, environmentally sealed product that can be mounted close to the antenna feed to reduce waveguide loss. 


  • Outdoor SSPA with integrated BUC
  • Compact, Lightweight Package
  • M&C capability via RS232, Ethernet
  • High linearity
