Hello , i've a 16 Mhz oscillator that produces 100 mV peak sine output . i'm trying to use that as a carrier to do ASK modulation but i think the power is too low to go to the antenna , so i tried to design a CE bjt amplifier for my carrier , i've a 9v battery as my supply , so i thought a gain of 90 would give me 9v p-p ,
i've set the emitter at 1v , calculated current Ic , and put the collector at half the supply , then i use a series resistance with bypass capacitor to set the Ac gain.
i've searched on the forums trying to learn how to design it properly and now i understand that my input voltage will cause the output to be distorted , but i have no idea how to calculate the distortion or how bad will it be ? , also i may be wrong in my entire design can i get a desired output from this circuit by adjusting R5 to get the right gain ?
