1. How to find the small signal AC voltage gain of a transistor (NPN) amplifier in common emitter configuration which has a emitter resistor (Re) with a capacitor (Ce) parallel with emitter resistor around 100 MHz?(transistor is BFR520, gainbandwidth product is 9GHz)

2. What will be the case if the Ce capacitor is not there?

3. Is it possible to get a small signal voltage gain of 25 at 100 MHz from BFR520 with the configuration stated above or what configuration will be the most suitable for this?
