In this tutorial you will build an rf amplifier using a high frequency bipolar junction transistor (bjt) with lumped elements. I had used the supply voltage as 15v.so the emitter voltage should be 10% of supply voltage.the emitter current should be same as collector current.so finally v= 1.5v and i=0.5a. As before, insert a blocking capacitor in the input signal.
