Hi,
I'm going to design a 100mhz amplifier.I have learned S parameters and amplifier design but I have some questions (because I've read designing procedures but don't have design anything)
1)when should we design with s parameters and when should we design according to pi transistor model?
2)how can find the maximum frequency of a transistor? is it ft? does we have any control of current to get our desire beta (beta*Ic=Ft)
3)what is bandwidth in transistor datasheet? does it define maximum frequency operation of transistor? or something else?
4)does we have any exist component for amplification between 30mhz to 120 mhz?(RF amp ICs)?
thanks
