I'm trying to design a power amplifier for the HF band to drive an inductive charger. The stage I'm working on now is a voltage amplifier which needs to be able to amplify 1 Vpp to 10 Vpp.
The input signal (1 Vpp) can vary from 5-15 MHz. The output signal will drive the MOSFET gates of the second stage, so it doesn't need to be able to provide a lot of current.
The question is what kind of circuit topology should I be looking at to solve this problem? Some configuration of BJTs, mosfets, op-amps? Also, what parameters do I need to look for in choosing the proper components?
It would be great if it was non-inverting, with little or no phase offset, but that is definitely not a necessity.
My First Try: I tried to build the circuit from this page, which says that a common-base amplifier is well suited for high voltage gain, and high frequencies. I chose this BJT to build it since it's specified as an RF transistor. Unfortunately, I can only get a little bit of gain around 10 MHz with the right biasing, but not with a 1V input, not anywhere near 10X, and it only works really close to 10 MHz.
