摘　　要：给出一种新型的通道功率合成式单刀四掷开关型(SP4T)发射机,利用两级通道功率合成技术,通过小功率开关的控制,使得高功率射频信号可以在四个方向中的任意一个方向带载切换。这种新型发射机具备带载热切换能力,使得发射机具备传统发射机所没有的高功率高速切换和高可靠性特点。A new type SP4T transmitter of channel power combined technique is presented. Using a low power switch's control and two stages channel power combined technique, the output port of high power signal is able to be switched to any one of four output ports. For the switched action is loaded, the new transmitters have a high reliability of high power and a high switch speed in contrast to traditional transmitters.
