This is an mini fm Radio transmitter circuit. The supply voltage is between one.1 � three Volts with power consumption is one.8 mA at one.5 Volts. This circuit ought to be able to cover 30 meters of range max. at one.5 Volts.
Note:
* Use a battery for powering the circuit.It will reduce noise.
* An FM antenna from a old radio is a better option than the wire antenna.
This device is NPN General Purpose Amplifier for use as a medium power amplifier and switch requiring collector currents up to 500mA.
