例句與用法
  • 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
    低價的、小型的、高性能的射頻收發前端的開發顯得越來越重要,本論文所研究的課題是ka波段倍頻鏈,要求把2ghz的信號倍增至36ghz 。
  • 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、毫米波系統中,性能優越的上變頻組件對系統性能起著關鍵性的作用。本文對毫米波上變頻器及其本振倍頻鏈的理論和設計進行了研究。
  • 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的混合頻率合成方案實現低端頻率2 ~ 4ghz的輸出,再通過分段放大倍頻鏈路實現從2 ~ 4ghz到2 ~ 12ghz的擴頻,并由微波開關控制選頻輸出。
  • 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
    根據本振倍頻系統的頻率高低將整個倍頻鏈系統劃分為分為兩條16 16的倍頻鏈并用獨立的腔體分開安裝。另外,考慮到在ka頻段進行三路功分很難保證三路本振信號等副等相,我們采取了在ku波段進行三功分,然后三路各自進行倍頻至ka波段的方案。
