All about 2n2222 transistor and its Circuit diagrams 2N2222 v s 2N3904: The 2N3904 is also an NPN transistor with same characteristics like 2N2222 but with one difference. It can control only one third of the current of 2N2222. As compared with 2N2222 it shows forward gain at lower current. 2N3904 is more useful in amplifier applications with fewer collectors current. FM Transmitter Circuit Working and Its Applications The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation (FM) transfers the information by varying the frequency of carrier wave according to the message signal.
