    • Systems and methods for hot standby of radio frequency (RF) power amplifier are disclosed, an auxiliary RF power amplifier is added and SPDT microwave switches are adopted at the input and output sides of primary RF power amplifiers to control whether to make the auxiliary RF power amplifier function. When a primary RF power amplifier fails, the auxiliary power amplifier can immediately take over the functions of the failed primary RF power amplifier without cutting off the power or stopping the operation of the whole system. SPDT microwave switches with multiple transmission lines and switch devices connected based on certain topologies are disclosed. The SPDT microwave switches have the functions of signal switching and power dividing and combining, simple circuit topology, excellent impedance matching characteristics or no reflected signals at ports, therefore the switches are highly practical and can be adopted in RF power amplifier hot standby systems.
    • 公开了射频(RF)功率放大器的热备用系统和方法,添加辅助RF功率放大器,并在主RF功率放大器的输入和输出侧采用SPDT微波开关,以控制是否使辅助RF功率 放大器功能。 当主RF功率放大器发生故障时,辅助功率放大器可以立即接管故障的主RF功率放大器的功能,而不会中断电源或停止整个系统的运行。 公开了具有多条传输线的SPDT微波开关和基于特定拓扑连接的开关装置。 SPDT微波开关具有信号切换和功率分配和组合功能,电路拓扑简单,阻抗匹配特性优异,端口无反射信号,开关非常实用,可用于射频功率放大器热备用系统。
