English abstract:
In this paper the performance of a digital quadrature PWM modulator for switched-mode wideband transmitters is evaluated. The purpose of the evaluation is to analyze the impact of the modulator parameter settings on the signal band quantization noise and on the average power efficiency of the complete digital transmitter. Considering a realistic setup at GHz range, the performance conditions for an accurate operation are studied as well. According to the results a higher average transmitter efficiency can be expected for a 10 MHz LTE signal excitation when compared with a similar modulator structure utilizing ΣΔ modulation.
