| Summary: | As the largest archipelagic state in the world, Indonesia has 17504 islands which are separated by the sea. 38 regencies and cities from 12 provinces in Indonesia are listed in the forefront and outermost regions. Difficulty of access and lack of infrastructures in the area may lead to potential telecommunication network cut off between regions which can cause state disintegration. One solution to overcome this is to use satellite communication that have much greater coverage compared to the Palapa Ring network that already exists in Indonesia. In 2022, Indonesia plans to launch Satria Satellites (Satellites of the Republic of Indonesia) which provides Ku band and Ka band services. The Ministry of Communication and Information together with the government made this satellite project as a step to encourage Domestic Component Level, for that the writer intend to design one of the main components of the satellite communication earth station, namely Block Up Converter (BUC) which functions as a frequency up-converter module and power amplifier for up-link communication.
In designing BUC, the writer carries out the design process that starts from problem analysis, literature studies, system design, simulation and prototype test then finally system evaluation. The system that is designed, in contrast to BUC in general, has a thermal compensation regulated by a microcontroller which also functions as an interface for BUC users. Users can directly configure BUC and get BUC operation data. From this final project, writer achieved a BUC design that works on the Ku band (13750 - 14500 MHz) with an output power of 36 dBm and can be adjusted via an interface that uses micro USB on the Teensy 3.5 microcontroller. From this final project, writer also produce Local Oscillator prototypes and interface of the systems that work at a frequency of 4383 MHz. |
