Abstract :
In this paper, a low-cost dual-port architecture for GFSK transmitters is investigated for its sensitivity to the path-delay difference between two data ports. The simulation results show that the architecture can achieve a high data rate but encounter significant modulation distortion due to the mismatch in path delay when the frequency deviation is close to the PLL natural frequency
