lna 例句

1. According to the application background and the dismatch between single antenna and differential lna , an active balun is needed and has been designed. then we put forward a design scheme that does co - simulation of an active balun and a differential lna on one chip together. at 2. 45ghz, this lna provides a forward gain of 28. 931db with a noise figure of 2. 485db, while drawing 19. 1ma from a 1. 8v supply
   從本設計的應用背景出發，考慮到單端天線與差分lna之間的不匹配性，設計了一個介於兩者之間的有源平衡轉換電路? balun （ balance - unbalunce ） ，並提出了將這個balun電路與前面設計的差分lna作為一個整體進行了模擬的設計方案。
2. Low noise amplifier ( lna ) is widely used in front end of a received set of mobile communication 、 wireless radio 、 blueteech technology and so on 。 the active device is the core of the circuit and has significant effects on the whole equipment, therefore, the design of the active device is vital in lna
   微波低噪聲放大器（ lna ）廣泛應用於移動通訊、無線電、藍牙技術等的rf前端。 lna中的有源器件是整個電路的核心，對整個放大器電路的性能有著重要的影響，因此有源器件的設計是lna的關鍵技術之一。
3. The lna with source inductor degeneration is analyzed in detail, which is used most widely in current. base on the analysis, a cascode structure is presented to minimize the effect of gate - drain capacitance cgd
   針對目前lna中應用最廣泛的源極電感負反饋結構，進行了詳細分析，在此基礎上對該結構做出了優化，採用共源共柵級聯結構，減小了柵漏電容cgd的影響。
4. Secondly, a method which can prejudge the gain and noise figure of the low noise amplifier ( lna ) is put forward. with this method, we can prejudge the feasibility of lna design once the s - parameter and noise parameter of the device are gained. the design process is considerably simplified compared with traditional methods
   隨后對低噪聲放大器進行了探討，提出了一種可預測增益和噪聲系數的方法，只要知道器件的s參數和噪聲參數，就能對放大器設計的可行性進行預測，相對于傳統作法，設計過程得到了大大簡化。
5. In this paper, the traditional cascode structure of cmos lna is considered as a two - stage amplifier and inter - stage matching network is introduced accordingly
   本文也對cmos低噪聲放大器進行了分析，將傳統共源共柵結構看作二級放大器級聯形式，並由此引入級間匹配網路。
