With the fast develop of technology and the various requirements of daily life, the demand of high-speed wireless communications becomes essential in recent years. For example, the fourth generation (4G) long term evolution (LTE) network cannot satisfy the needs of higher broad band, low latency and massive machine communications due to the limited bandwidth resources compared with the current deploying fifth generation (5G) new radio (NR) network. Besides, the next generation communications such as the non-terrestrial network (NTN) are also considered to enhance the 5G communications to have the advantages of service ubiquitous, service continuity and service scalability. Therefore, how to evaluate the new technologies and new spectrum behaviors become a critical issue to cope with the fast developments. One of the solutions is to adopt the software defined ratio (SDR) to test the performances of the new proposed methods. In this paper, we implemented the 5G SDR transceiver by using the field programmable gate array (FPGA). The proposed SDR has the advantages of the flexible operating spectrum, customized signal format, and wider signal bandwidth. With proper hardware replacements, such as mixer, filter, and antennas, the implementation can be operated at the desired spectrums.
