Re: "S or Y" parameter of transistor (Rf tran
Hi~~
If you cannot find the parameters in the datasheet, you may measure it using some network analyzer. Then, you will beed a zig to measure the s-parameters, providing a operating point of the transistor. The zig is requied to match the impedences correctly. If you once get the s-parameters, you can convert them into the y-parameters, using some conversion formula, which can be found in some books, on the internet, and in the manual of the network analyzer.
Bye~~
