27mhz Remote Control Transmitter Schematics Pdf

A remote control transmitter is a device that sends signals to a receiver, which then controls the operation of an electronic device. Remote control transmitters are used in a wide variety of applications, including televisions, radios, and toys. 27mhz remote control transmitters are a type of radio transmitter that operates in the 27MHz frequency band. This frequency band is unlicensed, which means that it can be used without obtaining a license from the government. However, it is important to note that 27mhz remote control transmitters can only transmit over short distances, typically up to a few hundred feet. The following schematic diagram shows a simple 27mhz remote control transmitter circuit. This circuit uses a 4017 decade counter to generate a 27MHz carrier signal. The carrier signal is then modulated by a switch, which is controlled by a button on the remote control. The modulated signal is then amplified by a power amplifier and transmitted through an antenna.
