Mini FM Transmitter

Posted on Feb 4, 2014

FM Transmitter is very simple, compact, and has transmission signal with a range of 100-150m, good sensitivity and low current consumption. Transmitter`s schematic consists of a bass amplifier for the first transistor and the proper frequency generator in the second. FM Transmitter divided transitional capacitor that allows you to set up a cascade separately.

Transmitter PCB shows the value of all the details and transistors! Reel contains 5 turns enameled wires 0. 35mm to send a diameter of 3. 2mm (rod of the handle). Setting frequency boils down to the installation shown in the pattern of voltages through appropriate resistors, and then check the current consumption ½ it should be about 10mA antenna ½ a piece of wire 40cm. Here you can see the bug assembly factory performance. FM Transmitter uses very small PCB and some SMD resistors.
