Communications solutions and case studies
Case study: Satellite communications
antenna
Satellite communication usually requires a large dish antenna. In addition, for moving vehicles, planes and boats antenna-positioning motors and controllers are needed to ensure that the antenna accurately tracks the relative position of the satellite. Mounting these cumbersome assemblies in a position to maintain a clear visual satellite connection is often impractical. This customer was developing an electronically steered solid-state phased-array antenna with no positioning motors to significantly reduce the antenna profile. The key goals were:
Factorized Power Architecture (FPA) separates the regulation and voltage transformation stages into separate components. The resultant design flexibility simplified the implementation and met the system requirements of small size and a low profile. Fast load response and high switching frequency eliminated many hold-up capacitors saving space. Key benefits were:
The Vicor VTM (transformation) supplied the high current 1.5V rail and was placed close to the ASIC. The PRM (regulation) was sited at the PCB edge since its 48V output bus to the VTM carried only low currents and provided reduced bus distribution losses. This arrangement saved space and optimized voltage regulation at the ASIC. To analyze this power chain, go to Vicor Whiteboard online tool.
