Design and Testing of Power Amplifiers for 5G and Beyond Wireless Communication

The development of the wireless communication system from 4G to 5G requires more spectrum bandwidth to transfer massive data. Sub-6 GHz frequency range which is below 6 GHz is one of the target frequency band for 5G applications. Thus, power amplifier which is one important component in the transmitter in the wireless communication system is required to operate efficiently at that band. The wide-band modulated signal for the 5G also introduces a wide dynamic range corresponding to a large peak to average power ratio (PAPR).

Monolithic microwave integrated circuit front-end module for satellite communication and next generation wireless communication applications

Front-end Module is key component in satellite and wireless telecommunication systems. It contains sub-modules like power amplifier, duplexer, antenna, low noise amplifier and etc. Advanced semiconductor technology enables the integration of these sub-modules. Compared to conventional bulky communication systems, this integration features compact size, lower cost, and higher performance. In 2019, the MMIC market reaches 7.7 Billion and increase to 10 Billion in 2022. The proposed project will use Gallium Nitride, the latest semiconductor technology, to design high performance MMIC chips.
