无线通信系统必须把接收天线接收到的单端信号转换成低噪声放大器(LNA)的差动输入信号。当然,可以在级联接收机链路中使用一个单端放大器,但是,单端—差动转换必须是在接收机链路中的双平衡差动混频器之前进行的。考虑到上述转换的难处,中国台湾新竹的国立应用研究所芯片制造中
Wireless communication systems must convert the single-ended signal received by the receive antenna into a differential input signal for a low-noise amplifier (LNA). Of course, it is possible to use a single-ended amplifier in the cascading receiver chain, but the single-ended-to-differential conversion must be done before the double balanced differential mixer in the receiver chain. Taking into account the difficulties of the above conversion, National Institute for Applied Applied Science and Technology in Hsinchu, Taiwan chip manufacturing
