2869.0/100 application field and working principle is related to a type of radio transmitters commonly used for FM broadcasting. Its operating frequency range is between 87.5 MHz to 108.0 MHz. It is an economical, efficient, and reliable single-channel PLL (phase-locked loop) FM transmitter. The transmitter is equipped with a standard 78L05 regulator, which means it can provide regulated voltage over a wide range of input voltages. This ensures the continuity of the signal over a range of input voltages, even during brief power fluctuations or when powered by battery.

The 2869.0/100 transmitter is designed to provide a constant rate of output power, resulting in improved signal stability and consistent audio transmission. It features an LCD for displaying the output frequency. The user can adjust the transmitter’s output frequency conveniently using the tuning knob. The transmitter offers wide-area coverage, allowing for voice or audio broadcasting over long distances. In terms of noise, the device features wideband noise suppression that eliminates noise from other frequencies when receiving a signal.

The receiver is made with power transistor technology, which increases the efficiency of the transmitter. This ensures the transmitter can output a high power signal while consuming a minimum amount of power. In addition, the device uses a VCO system to ensure a stable frequency during transmission. Its gain control allows users to adjust the transmitter’s sensitivity and power output, enabling them to ensure clear and consistent audio transmission over a wide area.

In terms of its application field, the 2869.0/100 can be used for FM broadcasting. It is ideal for AM radio or television broadcasting, as well as for broadcasting short-range voice paging, such as restaurant pagers or medical alert pagers. The device is also commonly used in hotels, schools, and other commercial establishments for voice paging. The device is also used in entertainment systems, such as bars, restaurants, and dance clubs, for background music. It can also be used for digital data transmission, such as the transmission of retail store inventory levels or other business-related data.

The 2869.0/100 transmitter employs the advanced PLL technology for frequency control. This ensures the device maintains a constant output frequency regardless of any changes in temperature or power supply. This technology also helps reduce noise from other nearby frequencies. The device is easy to use and does not require any additional components for installation or operation. Additionally, the device is easy to monitor, with the LCD indicating the output frequency at all times.

The transmitter also features a wide range of features such as adjustable output power, wide-area coverage, wide-band noise suppression, and adjustable gain control. This allows users to customize the device to their specific requirements, ensuring the best possible audio quality. The user can also adjust the sensitivity of the transmitter to ensure a clear and consistent signal, even over long distances. The transmitter also features an LED warning indicator that alerts users to any eventualities that may arise during transmission.

The 2869.0/100 is a reliable transmitter that provides high-quality audio transmissions over a wide area. It is an efficient, economical, and robust single-channel PLL FM transmitter, making it an ideal choice for radio and television broadcasting, digital data transmission, and voice paging. The device features adjustable power output, wide-range coverage, noise elimination, and adjustable gain control, enabling users to customize it to their specific requirements. It is also easy to monitor, set up, and operate, making it an ideal choice for commercial establishments and entertainment systems.
