hello kk
I am also involving in a low power CMOS RF IC transceiver design
maybe we can discuss it.

You could just buy one and say you built it from scratch?

why you do not want to discuss with all

please tell the specifications ifyou have any

The case is I do not have specification right now
I am trying to do the system level simulation to find out these specification

Hi,
you may want to try Microwave System Calculator.
To build a line up can't be more easier!
It has been designed just to be used for problems similar to your.

Oh ... yes ... it's free!
