Broadband matching is very difficult , but we can make it easier with negative feedback and balanced amplifier . so at first we should choose a project , then according to the requirement of the low noise amplifier to choose the transistor , bias and matching
宽带匹配网络的设计是一个难点,可以采用负反馈、平衡电路等形式降低宽带匹配的难度,所以宽带电路的设计首先是方案设计。
In the sixth chapter a low noise amplifier whose operating frequency is 6ghz 12ghz is presented . it is a balanced amplifier . in this chapter we discuss the calculation of lange coupler , the matching of balanced amplifier and the influence of thin film mic in the design
第六章设计的6ghz 12ghz的低噪声放大器为平衡放大器,详细讨论了兰格耦合器的计算、平衡放大器中匹配电路的设计和薄膜mic工艺对电路设计的影响。
