how to write specification for transmitter? Answered

I trying to write specification for transmitter that transmit voice signal over 100 meter long at 97 mhz frequency

modulation type
Input voltage 12 v
input current 9 mA
input power

output voltage
output current
output power

operating frequency 92 - 97 Mhz
oscillator circuit that generate 97 mhz frequency
transmitting distance 100 meter long

how to decide how much output voltage and current I need at output side ?

If the input power is 12V @ 9mA then the input power is 108mW. Output power and all will depend on the circuit being used. You'll have to build it and measure it.
