impedence transformation

a question about impedence transformation
I want get 50 ohm source impedence transformation to 0.9/+25 (gamma),I'm using smith chart to doing,but I have a problem ,please see the pictures follow...

i tel u y , coz in ur schematic , u used both terminations are 50 ohms
u need to change term 2 to the impedance of the load , and things will work

Thanks you very much!

1.I'm sorry I don't know what is my circuit's load impedence,Because I use this circuit to transform 50 ohm source impedence to 0.9/+25deg for min noise matching.
2.Can you tell me why I need chang term 2 to impendece of load?

Thank you!

Why are you using 50 Ohm term? Is it because the S-param simulation?

u need to change term 2 to ur load impedance , to check the matching , so u need to know how ur circuit will convert the 5o ohm of the source to the load

Thank you very much!

But I still have some problems:
I want transform 50ohm source impedence to 0.9/+25deg (53.2+j212.9) Zout,now I changed Term 2 impedence to 53.1+j212 ,after simulate I found the VSWR(S22) is 1.06 like conjugate match between Zout and Term 2,So I think the impdence of Zout is 53.1-j212(0.9/-25deg) ,But in smith chart ,I just from 0.9/25deg to move to 50ohm point.

Thanks in advance!

anyone who can help me?
