Hello everyone I want to model avago tech atf series transistor in AWR MWO .I have s parameter of the transistor and my question 1 is
can I import impedance parameter of s parameter data to NL_AMP block or should I use LPTUNER for the modelling
second one is can we import impedance data LPtuner or not
If you know nonlinear characteristics of ATF at certain frequency, you can replace these specs. ( Gain, IP2,IP3,NF etc. ) in NL_AMP block with ATFs numbers but it won't be replaced 100% beause you cannot touch internal impedances and other small signal parameters so this wouldn't be a 1 to 1 replacement.
Why don't you use nonlinear model of ATF ? It will give you all ( small signal and nonlinear both ) charateristics.If you are able to use ADS, download the design kit for ATF54143 and install it then open the sub-circuit schematic and create this sub-schematic with all linear and nonlinear elements on to AWR.So, this will be replica of ATF..
Or simply request from Avago Tech..
Just a quick remark..
I have done some simple simulations in ADS, MWOffice and Nexxim and I have found pretty different results in 3 simulators even the bias conditions and other stuffs are exactly same.It was a very simple ideal A-Class small signal amplifier and the results are quite discrepanced in especially HB results.
So, creating a 1:1 replica in a different simulator may not work well.I guess the simulators interpret some models in different manners...
It seems to me weird..
