Thanks JoeJester and Bertus.
there are several more questions regarding components:
1) TI, is it stands for Texus Instrument? I couldnt find the way to download the model from it.
2) Is it possible to do the vco by using discrete componet instead of using IC? because I couldnt find the perfect vco which can work in the frequency of 13.5MHz except POS25. however, POS25 is not available in pspice.

Thanks for the info retched.
Bertus, the list that you gave me is for op-amp with greater than 50MHz isnt it? but I need only up to 13.5MHz.

Hello,

To have an opamp working at 13.5 MHz the gain-bandwith product must be higher.
The opamps in the "greater that 50 Mhz" list will probably work at 13.5 Mhz, depending on the gain you need.

so, basically, HA17741 is not suitable for the one that I am working with now? Ill be changing with another suitable op-amp then.thanks Bertus.
