Özet
Amplifiers are of great importance for linear, efficient and stable satellite communication (SatCom). It is necessary to design circuits at different frequencies according to the uplink and downlink applications used in this type of communication. Filtering unnecessary frequencies with a band pass filter (BPF) circuit, amplifying weak signals with a low noise amplifier (LNA), and increasing the power to be transmitted with a power amplifier (PA) are also among the tasks that need to be done. In this study, a design that is valid for uplink services and can be used in SatCom has been made. BPFs, LNA and PA topologies are used together in this proposed circuit. Chips produced by Hittite company were used for LNA and PA. The LNA S21 parameter is approximately 26 dB; the gain has been increased around 48 dB with the PA. The studies were carried out on the AWR tool, between 8 and 20 GHz, especially in the IEEE Ku band (12-18 GHz) which includes uplink frequency windows, 14-14.50 GHz for safe wireless communications. © 2023 Elsevier Ltd.
