Camera VHF Video Transmitter

This is a simple video transmitter capable of transmitting signals up to 50 meters. It can be utilized with cameras or other video sources and allows viewing on VHF channel analog televisions. The video transmitter operates on a supply voltage of 9V, which can be provided by a battery. The transistor used in the video transmitter can be a BC548 or an alternative type such as BF199. Other components utilized in the design are SMD (Surface Mount Device) type. The coil, labeled as L1, consists of 5 turns with a diameter of 8 mm, using wire with an AWG rating between 0.3 and 0.5 mm.

The video transmitter circuit is designed for efficient transmission of video signals over short distances. It operates within the VHF frequency range, making it compatible with standard analog televisions. The choice of transistors, such as the BC548 or BF199, is critical for ensuring adequate amplification of the video signal, allowing for clear transmission at the specified range.

The power supply, a 9V battery, is suitable for portable applications, providing the necessary voltage for the circuit operation. The use of SMD components is advantageous as it allows for a more compact design, reducing the overall footprint of the transmitter. SMD components also contribute to improved reliability and performance due to their smaller size and lower inductance.
