RFM12B - 868Mhz Wireless FSK Transceiver
add to cart
The RF12B is a low power, multi-channel FSK transceiver designed for use in applications requiring FCC or ETSI conformance for unlicensed use in the 433, 868 and 915 MHz bands. The module is a complete analog RF and baseband transceiver including a multi-band PLL synthesizer with PA, LNA, I/Q down converter mixers, baseband filters and amplifiers, and an I/Q demodulator. All required RF functions are integrated. The RF12B features a completely integrated PLL for easy RF design, and its rapid settling time allows for fast frequency-hopping, thus bypassing multi-path fading and interference to achieve robust wireless links. The RF12B dramatically reduces the load on the microcontroller with the integrated digital data processing features: data filtering, clock recovery, data pattern recognition, integrated FIFO and TX data register. For low power applications, the RF12B supports low duty cycle operation based on the internal wake-up timer.
