Implementation of Radio Frequency Digital to Analog Converter Design for Satellite Telecommunication System

In satellite communications applications, the radio frequency digital to analog converter is a crucial building block. Radio frequency digital to analog converter (RFDAC) is the fundamental link between analog and digital electronics. The DAC converts the input digital signal into an equivalent analog output signal. Dynamic performance is high-speed and high-resolution digital to analog converters (DACs) limit the distortion at the data switching instants. For this paper, 8 bits digital to analog converters are designed by using the Flash method. A D/A converter simulation circuit converts the parallel digit bits (do~d7) to the analog voltage equal to the original sample with some quantization errors. These ADC bits are summed and differed by using the Flash method to produce the digital pulse string. This production can write by using high-level language for the digital signal processing (DSP). The digital pulse string of digital signal processing (DSP) passes through DAC block for the required analog output signal. The MATLAB programming is used to simulate the required ADC, DAC and DSP functions and the post analysis of simulated results.
