例句与用法

1. So the low price , small bulk and high performance of front - end rf become more and more important . in this dissertation , a ka band multiplier chain is developed , which can be used for local oscillator
   低价的、小型的、高性能的射频收发前端的开发显得越来越重要，本论文所研究的课题是ka波段倍频链，要求把2ghz的信号倍增至36ghz 。
2. In the microwave and milli - wave system , the performance of the up - mixers play a key role in the whole system . this dissetation make a research in the theoretics and design of the milli - wave up - mixers and the lo multipliers
   在微波、毫米波系统中,性能优越的上变频组件对系统性能起着关键性的作用。本文对毫米波上变频器及其本振倍频链的理论和设计进行了研究。
3. This paper introduces the realization scheme and key technology of 2 ~ 12ghz ultra - wideband microwave frequency synthesizer . it adopts dds + pll frequency synthesizer scheme to realize low end frequency 2 ~ 4ghz output , then through segment amplifying multiplying chain realize from 2 ~ 4ghz expand to 2 ~ 12ghz , and the output frequency is selected by microwave switch
   采用dds + pll的混合频率合成方案实现低端频率2 ~ 4ghz的输出,再通过分段放大倍频链路实现从2 ~ 4ghz到2 ~ 12ghz的扩频,并由微波开关控制选频输出。
4. 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。
