Hello, there are two problems.
1. I have seen that someone design a SiGe MMIC circuit, like LNA, divider, or even an receiver at 60GHz in cadence, but we could not do EM simulation in cadence as the lines in the circuit must be considered to be transmission line in such high freq. my question is that how do we deal with the lines and the EM coupling between components so that we can obtain the expected results?
2. In the MMIC design in SiGe BiCMOS or just CMOS RFIC, how do we consider the interstage matching, for example, the input of LNA is 50 Ohm, how can I consider to be the output of LNA as the next stage of LNA is the mixer, but the mixer have not been design yet? That is to say, I am confused about the circuit blocks connection in RFIC or MMIC system, can anyone explain in detail?
Are there any books or papers recommended about these problems?
thank you all!
Wish you good luck!
