有人危言耸听说RFIC将来5年后找不到工作

个人觉得至少有三个模块无法消失
1. LNA
2. ADC/DAC
3. Frequency Synthesizer

况且SDR对ADC DAC要求太高,powe is staggeringly high, which means sdf can't find a place in consumer electronics markets,where power constraints are very tight.
One trend observed in personal wireless roadmap is that higher-PAR modulation schemes are increasingly adopted, such as QAM, OFDM. Placed in a SDR scenario, these modulations pose even higher dynamic range of ADC & DAC, i.e., ENOB.

However, in less power-sensitive applications such as basestations. SFD will be a competive contender.

现在的模拟电路是加入了越来越多的数字模块了，因为电压降得太低了，所以很多传统的结构都不管用了，其实是给工艺的进化逼得，但是纯数字的电路想要取代射频，我想除非工艺出现革命性的变化，mos工艺这么演化下去也不太可能做到，同时高频应用也越来越多了，比如下一代无线个域网标准频谱是60GHz，附近的，现在你能想象工作在60GHz的数字电路么？

放心吧,不会的

在大家还没退休前估计数字还无法完全取代模拟的

模拟域中很多问题是数字无法解决的，比如噪声，线性度等

还有一个模块就是PA也绝不可能消失

找不到工作还要五年后吗？

国内没戏。。。

做工艺最好。
