hi guys ,? please i need your Help. how do i make a transformer in Ltspice ? with best Regard .

Thanks, guys. Under linux, life is slightly different. Unless I am running an m$ program already, wine is always rebooted. There is this "wall" between 'windows' and linux and the idea of windows

Hello, I found the reason why LTspice didn't update in my case. When you have opened the LTspice Yahoo group, your web browser window will have th title name "LTspice IV - Groups - Mozilla Firefox".

Hello Kalias, Has this model better worked? ** Product: MMBTH81 ** Package: SOT-23 ** PNP RF Transistor *----------------------------------------------------------------- .model MMBTH81 pnp +

Actually I think we are in complete agreement. I just misunderstood the intent of what you wrote before. My bad. Regards, Andy

Thanks Helmut, I took a look there but didn't see this model. I ended up taking one from the datasheet. cheers kalias

Hello, Please try this model from Fairchild-Semi. Click on "RF Transistors". http://www.fairchildsemi.com/models/modelDetails?modelType=PSPICE#resultDiv ** Product: MMBTH81 ** Package: SOT-23 ** PNP

Hi, thank you for your reply. When you get the chance, I would appreciate if you could re-upload it. Thanks a lot Marco

Thank you sir for your valuable help.

I am trying to create a model for the MMBTH81 transistor. I extracted the following model from the datasheet and put it in a LTspice schematic with a directive. .MODEL MMBTH81 PNP(Is=10f Xti=3 +

John Woodgate asked: This is all good stuff, but could you please comment in the OP's You need at least two time samples at the highest frequency of the FFT. 1/90MHz * 0.5 = 5.56 ns Helmut's example
