问个RFIC问题

请各位大侠多多指教

At low giga-hertz, there is no much to do now.
Maybe:
very high dynamic range receiver, digital phased-array, and mimo radar chipsets for the defense applications.

谢谢您的回复，另外RFIC的电磁分析有必要做么?就是用数值方法去模拟

RFICs usually refer to low giga-hertz radio chips. Inter-connections can be treated as RC parasitics, and therefore EM simulations are not necessary; unless the lines are very long, and should be modeled as transmission lines.
Spiral inductors and transformers should be EM modeled for circuit simulations.
