倍频系统 meaning in English
frequency doubling system
Examples
- Because the phase noise of the input crystal oscillator is excellent to 150dbc @ 10khz , we don ’ t adopt the pll method to yield the lo souce , but multiply the input signal . for to discard the harmonious frequencies yield by the multiplier , we have connected narrow - band filter between the circuit , and connected the isolator to reduce the interferes bring by the feedback signal of the amplifier . according to the frequency of the lo system , we aparted the whole lo system to two subsystems , and fixed in the different capsules
根据本振倍频系统的频率高低将整个倍频链系统划分为分为两条16 16的倍频链并用独立的腔体分开安装。另外,考虑到在ka频段进行三路功分很难保证三路本振信号等副等相,我们采取了在ku波段进行三功分,然后三路各自进行倍频至ka波段的方案。
