Modern RF systems consist of high-frequency analog electronics (the front end) and adaptive digital algorithms. One of the primary challenges in RF system design is reducing the overall area, power, and cost for RF front ends—generally wireless transmitters and transceivers. For this reason, smar...
一般的RF powder system由三大部分组成,分别为:(1)射频电源(RF generator),(2)传输线(transmission line),(3)阻抗匹配系统(impedance matching system)。 射频电源(RF generator)是用来产生射频电功率的电源,输出一般是正弦波或脉冲,输出功率从几十瓦到几十千瓦,输出阻抗一般是50欧姆,频率有2MHZ、13.56MHZ和60MHZ...
