Hey guys,.........I have a problem here that i have for HW and was wondering if anyone could help me out or point me somewhere that might be able to..... Here's the question:

"It is desired to connect a 2GHz oscillator to a high speed cpu as shown in the figure below. The ineral impedance of the oscillator is 50+j50 ohms. The cpu is in turn connected to a high speed RAM as shown in the figure. however, the RAM runs at a frequency of only 200Mhz. Design the two matching networks shown in the figure if the cpu and the ram have the same s-parameters shown below:

S11 = 0.4 @ 162
S22 = 0.35 @ -39
S12 = 0.04 @ 60
S21 = 5.2 @ 63"

I know the frequency has little to do w/ anything until the end for finding the ipmedance values. The way we were taught was to use the load reflection coefficient and the starting impedance for graphing on the Smith Chart to find out the impedance of the matching circuit. However, there are two matching circuits that need to be found, so this isn't as easy of a thing to do. I emailed the professor and he said that for the second matching circuit to use a reflection coefficient instead of an impedance value but i don't know whether or not to use the source or the load reflection coefficient. If anyone can help me out that'd be much appreciated even if it's just directing me to a better place to post this (which i'm looking for now)....

Sorry man, if you had a purely digital system I could help you. Well, maybe; it might not be what your prof is looking for. Not to mention the fact that I just took an electronics final today and really don't want to think about electronics for a while. Good luck with that problem though.
