Filed: 1989-12-08
Abstract: PURPOSE:To reduce power consumption in transmission equipment by providing a transmission signal point recognization circuit and a bias control circuit, and controlling the saturation output of a power amplifier with the vector length of each signal point of an analog multivalue signal after converting a digital signal to be transmitted to an analog signal. CONSTITUTION:The transmission signal point recognization circuit 1 inputs the multivalue signal after converting the digital signal to be transmitted to the analog signal, and judges the signal points A, B, C, and D of the multivalue signal with prescribed vector length, and sends them to the bias control circuit 2. The control circuit 2 generates a bias control signal (c) corresponding to each prescribed vector length of the signal points A, B, C, and D, and sends it the power amplifier HPA 16 at a transmission final stage. Then, the saturation output of the HPA is controlled by controlling a DC bias to decide the operating point of the power amplifier HPA. Therefore, since the saturation output of the HPA is changed corresponding to the prescribed vector length of the signal points A, B, C, and D of an input multivalue signal to perform analog multivalue QAM modulation, the average power consumption of the power amplifier HPA can be reduced.
