正向增益

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
从本设计的应用背景出发,考虑到单端天线与差分lna之间的不匹配性,设计了一个介于两者之间的有源平衡转换电路? balun ( balance - unbalunce ) ,并提出了将这个balun电路与前面设计的差分lna作为一个整体进行了仿真的设计方案。
