Techniques to reduce the cost of the satellite base solutions

This paper presents the techniques to reduce the cost per bit of the satellite communication technology by providing flexibility of operation and improving the power efficiency of the Solid State Power Amplifier (SSPA). Improvement in power efficiency results in reduced DC power generation on-board, improved thermal performance and launching cost for space segment of Geosynchronous Satellite Communication. The flexibility allows user to keep themselves with the changing scenario of satellite communication. Using this concept, the Gallium Nitride (GaN) based SSPAs will surely replace the TWTAs for on-board applications also. It also demonstrates the circuit topology for selecting the required narrow frequency band rather than designing broad band SSPA resulting in improvement of Power added efficiency, channel temperature and reliability of the active devices.
