i want to design microphone pre amplifier circuit for am transmitter
AM TRANSMITTER
(i am not sure my specification is right or wrong i consider only for mathematics
modulations type am modulations
frequency range 2mhz
voltage supply 12v
transmitting distance 80m-100m
audio frequency 20hz-20khz
antenna
microphone specifications(i am not sure consider only for mathematics)
frequency response 20hz-20khz
sensitivity 40db at 1hz
s/n ratio 60db
output voltage of microphone=50 micro V
output current of microphone=10micro A
how to calculate the gain needed for pre amplifier
which stage of transistor should i use
thanks everyone
