DF data transmission module and the super-regenerative receiver module

The DF data transmission module operates at a frequency of 315 MHz and utilizes a surface acoustic wave (SAW) resonator for frequency stabilization, ensuring high frequency stability. The frequency drift remains minimal, at only 3 x 10^-6, across a temperature range of -25°C to +85°C. This module is particularly suited for applications involving multiple wireless remote controls and data transmission systems. Wireless data transmission is extensively utilized in various fields including industrial data acquisition systems, compact wireless data terminals, vehicle monitoring, remote control, telemetry, access control systems, paging, identification, non-contact RF smart cards, fire safety systems, and more.

The DF data transmission module is designed for robust performance in environments where temperature fluctuations can impact the reliability of electronic communications. The SAW resonator technology provides a stable frequency reference, which is crucial for maintaining the integrity of data transmissions in critical applications. The low frequency drift of 3 x 10^-6 ensures that the module can maintain accurate communication even under varying environmental conditions, making it ideal for long-range and reliable wireless systems.

In terms of its equivalent circuit, the DF module likely includes components such as resistors, capacitors, inductors, and the SAW resonator itself, arranged to optimize signal integrity and minimize losses. The circuit design would typically focus on impedance matching to ensure maximum power transfer and reduce reflections. The module's design may also incorporate filtering elements to suppress unwanted harmonics and noise, further enhancing the clarity of the transmitted signal.

The applications mentioned, such as industrial data acquisition and vehicle monitoring, highlight the versatility of the DF module. In industrial settings, it can facilitate real-time data collection from various sensors, while in vehicle monitoring, it enables tracking and telemetry functionalities that are critical for fleet management. Moreover, the module's use in access control systems and fire safety applications underscores its reliability and importance in safety-critical environments.
