Modern satellite communication systems require high data rate, high-efficiency and simple transmitters, without sacrificing efficiency and linearity depending on the modulation scheme. Main purpose of this study is to design a transmitter with data rates up to 100 Mb/s, BPSK/QPSK/OQPSK modulation and 7 W output power at 8.2 GHz for low Earth orbit (LEO) satellites in order to satisfy the high data rate demand. Since the transmitter should be a low power, simple and low weight one, the power amplifier will be a solid state device. The power consumption of the transmitter is mainly determined by power amplifiers, which should be improved according to these constraints. In the oncoming stages of this study, the linearity and efficiency trade off for BPSK, QPSK and OQPSK modulated signals in this line-up will be observed.
