FOREMOSTLY, does orcad even support RF designs ( say frequencies up to 10GHz)? currently, i am designing a low noise amplifier using all the trial software versions that are available online. The orcad pspice is one alternative, but i'm a bit weary on the simulation results that i am getting. another thing, for a cmos rf LNA design, it would be best for me to implement a 4-terminal mosfet device into my design..however, i cant find a 4-terminal nmos (or pmos) model in the orcad library. all of the available models are 3-terminal model devices ( NMOS device with a source-body tied configuration ). What can i do? HELP!!!! Thanks in advance!
