Problems solved by technology

[0011] The main disadvantage of this solution is that the sampling frequency of the current high-performance DAC is low, and the high-performance DAC and high-performance ADC will significantly increase the design cost of the solution. For high-carrier modulation signal output, the internal processing of high-speed data signals in the FPGA will consume more resources in design and signal processing, increasing the difficulty of design
The carrier modulation signal can only use the digital intermediate frequency scheme, and then cover higher carrier frequency through broadband up-conversion, the analog circuit design scheme will become more complicated, resulting in higher intermodulation and spurious signals
