Abstract
This paper introduces a compact digital transmitter for SNG specialized to portable operation. This system has several features. (1)This system requires only 0.75m diameter of the parabola antenna. (2)We have adopted 40 watt(W) HPA in order to lighten its weight; to make it small; to reduce the consumption of the electric power. (3)This system adopted MOK-QPSK digital modulation for the purpose of transmission in the saturated region of the power amplification.
