例句與用法

So , we must research and develop a kind of receiver with good expansibility that the working frequency band is wide , and the adaptive capacity of the wave form is strong
所以,必須要研究開發(fā)一種工作頻段寬,波形適應(yīng)能力強(qiáng),可擴(kuò)展性好的接收機(jī)。
This subject aim at designing a linear power amplifer whose output power is 40w for 225 - 450mhz band . but it seems not easy to finish the task because of this power amplifier own unique requirements including high output power , broad working frequency band , high linearity , and flat gain . due to the complexity involved , theoretically several soltuions are derived in the final scheme such as broadband matching technology , power - retreat , power synthesize , automatic power control and negative feedback . in addition , the design will be optimized by eda software and the final test result indicates that our design is successful
本課題的目標(biāo)是研制一個(gè)輸出功率為40w的225 450mhz的線性功率放大器。由于該功放要求輸出功率大，工作頻帶寬，帶內(nèi)增益波動(dòng)小，線性度高，所以其終合設(shè)計(jì)難度大。鑒于這個(gè)原因，在理論設(shè)計(jì)上筆者采用了寬帶匹配、功率合成、功率回退、負(fù)反饋、自動(dòng)功率控制等技術(shù)；在實(shí)踐中精心設(shè)計(jì)電路，并且配合eda軟件仿真，最終達(dá)到所要求的指標(biāo)。
