Novel RF architectures and technologies for VSAT
Very Small Aperture Terminal (VSAT) systems provide satellite communication solutions for users where terrestrial technologies are either uneconomical or simply non-existent. VSAT ground terminals conceived to date are largely based on conventional RF architectures, which make use of bulky, high power and/or costly components. The continuous downwards pressure on the price and form factor of VSAT terminals requires a major evolution of the associated RF hardware - in terms of higher packaging density, lower power dissipation and optimized frequency stability. This paper describes the recent developments in the field of ground segment RF architectures and technologies and provides an overview of relevant R&D opportunities for VSAT terminals.
