探讨如何进行射频载波抵消以及检测放大器互调失真信号。
How to cancel carrier and detect the intermodulation distortion signal of power amplifier will be discussed.
所以射频载波信号即可由System40主机中的同轴继电器进行路由。
Therefore, the RF carrier signal is routed by coaxial relays in the System 40 chassis.
调幅讯号之频谱为一半强度基频讯号之频谱分别正负位移一射频或载波之频率。
The spectrum of amplitude modulated signal are two half magnitude spectrums of base band signal positive and negative shifted by a carrier or R. F. frequency.
结果表明，射频信号的驱动电压，系统中偏振态的变化是影响频率锁定多载波光源产生的主要因素。
The results show that the radio frequency drive voltage, the variation of states of polarization are main factors to affect the generation of the frequency-locked multi-carrier source.
另外，采用软件无线电能进行多载波处理，减少射频通道数，缩小体积，节约成本。
Additionally, another advantage of software radio is that it can process multi-carrier, decrease the RF channel, lessen the devices 'solidity, and save the its cost.
