微波电阻对射频系统的稳定性分析

Stability Analysis of Microwave Resistance to RF System

对于射频系统来说,性能指标是需要重点关注的部分,且系统的可靠性和稳定性也至关重要。因此,在保证射频性能不变的条件下,通过系统模块输出匹配状态和开路状态改变模拟射频系统的传输状态,讨论实验数据分析,运用相关理论推导得出结论——在射频电路中,射频模块输出匹配电阻耐功率值需是正常工作功率的2倍。

For radio frequency system,perfomance is to pay close attention,in addition,stability and reliability of RF system is very important.In this paper,uder the conditions of no change for frequency system perfomance,The transmission state of radio frequency system is simulated by system output part matching state and open circuit state.The test data analysis is discussed and the relevant theory is used to derive.It can be concluded that in the RF circuit,the matching resistance value of the RF system output should be 2times the normal working power.
