<p>Two kinds of radio frequency power amplifier hot standby system and method, add the backup radio frequency power amplifier in the system, and use the microwave single-pole double throw switch at the input end and the output end of the radio frequency power amplifier respectively to control whether to use the backup radio frequency power amplifier. When one of the power amplifiers is at fault, the backup power amplifier, if it is not outage, will replace the fault power amplifier to operate and realize the backup function immediately, and it has very high separation. Two kinds of microwave single-pole double throw switch are constituted by connecting multiplex transmission line and multi-binistor according to the certain topology, the microwave single-pole double throw switch has the function of signal switch and has the power distribution and sub-circuit function, and the circuit is simple, there is not reflected signal at the port or it has good impedance matching characteristic, and is very practical. It can be used in the radio frequency power amplifier hot standby system.</p> |
