SRWF-1022 SRWF-1022, the low-power wireless transceiver module is used as the wireless command transceiver in short-ranges, with the small size, weight and power consumption and good stability and reliability. Narrowband low power UHF wireless data transmitters: II. Feature of SRWF-1022 Low Power RF Module 1. Using oscillator instead of crystal. The work temperature with oscillator is -40℃ to 80℃(with crystal is -25℃ to 75℃). 2. High reliability, small and light Single chip radio - frequency integrated circuit and single chip MCU are used for lessened peripheral circuits, high reliability, and low false bit rate. 3. ISM frequency band, requiring on application of frequency point. Carrier frequency of 470.5~479.5MHz. 4. High anti- interference and low BER(Bit Error Rate) Based on the GFSK modulation mode, the high- efficiency forward error correction channel encoding technology is used to enhance data’s resistance to both burst interference and random interference and the actual bit error rate of 10-5~10-6 can be achieved when channel bit error rate is 10-2. 5. Low power consumption +5V supply power, receiving current is 30±3mA。 III. technology support and after service : Serial number Item Parameter Note 1 Modulation mode GFSK 2 Work frequency 470.5~479.5 MHz 3 Receive sensitivity -117 dBm 1200bps@470.5MHz 4 Transmitting current 90±10mA 5 Receiving current 30±3mA 6 Sleeping current 5±2uA 7 Interface velocity 1200/2400/4800/9600/19200bps 8 Interface mode VCC,GND,GPIOs
