433M RF Wireless Module
RXB12, the working frequency of data transmission module is 433Mhz, using acoustic meter resonator SAW frequency stabilization, frequency stability is very high, when the ambient temperature changes between -25 ~ +85 degrees, the frequency wave is only 3ppm/ degree. Applicable scope, especially suitable for multiple wireless
RXB12 remote control and data transmission system. The frequency stability of acoustic meter resonator is second only to that of crystal, while the frequency stability and consistency of general LC oscillator are poor. Even if high-quality fine-tuning capacitor is adopted, the temperature difference and vibration are difficult to ensure that the tuned frequency point will not shift. RF Transmitter Module does not set up a coded integrated circuit, but adds a data modulation triode Q1.
