If you're just buffering or amplifying a fixed frequency signal, why not use an RF transistor as an amplifier instead of an op amp?
buffering/amplifying non fixed signal shape and frequency, it could be arbitrary signal, the FG in question is Hantek 3x25 Arbitrary Function/Wave Generator.
i'd love to use transistor as well. but since my knowledge is very limited, a simple link(s) info on "transistor as a high frequency amplifier" could be very helpful.
and last time while looking for audio amp circuit, to be able to generate +ve to -ve signal (pure sine?), we need several setup and stages of transistors and have to deal with clipping/distortion at "near 0V" region.
thanx allanw for the advice. isnt an oscilloscope enough for that simulation? ie make the real circuit and debug?
ps: and i have this in mind... auto balancing bridge for impedance analyzer using the high speed op amp (i'm reading the agilent 5968-4506E.pdf

)
