Description: FM Transmitter 45W with valve. TECHNICAL CHARACTERISTICS: Power supply: 220V AC Frequency range: 88~108MHz Output power: max 45W.
The FM transmitter described operates within the frequency range of 88 to 108 MHz, which is the standard FM broadcasting band. It utilizes a valve (or vacuum tube) technology, which is known for its ability to produce high-quality audio signals and is often preferred in high-power applications due to its robustness and linearity. The transmitter is designed to operate with a power supply of 220V AC, ensuring compatibility with standard mains electricity in many regions.
The output power of the transmitter is specified to be a maximum of 45 watts. This power level is suitable for local broadcasting applications, allowing for a significant coverage area depending on the antenna used and environmental factors. The use of valves in this transmitter may contribute to a distinctive sound quality, which is often sought after in certain broadcasting scenarios.
In terms of circuit design, the transmitter would typically include several key components: an oscillator circuit to generate the RF signal, a modulator circuit to encode the audio signal onto the RF carrier, and an amplifier stage to boost the power of the signal before transmission. The valve technology would primarily be utilized in the amplifier stage, where it can efficiently handle the high power levels required for effective transmission.
Additionally, the transmitter may include various protection and control features, such as automatic gain control (AGC) to maintain consistent output levels, and over-temperature protection to prevent damage to the valves during prolonged operation. Proper heat dissipation mechanisms, such as heatsinks or fans, should also be integrated into the design to ensure reliability and longevity of the transmitter.
Overall, the FM transmitter is a specialized piece of equipment that combines traditional valve technology with modern engineering practices to deliver a reliable and high-quality broadcasting solution.Transmitter FM 45W with valve.
