SRWF-1022 User Manual (V1.1)
I. 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。

There is one group of 5-bit short-circuit wire (JP2) on the bottom right corner of
SRWF-1022, defined as A、B、C、D、E respectively . A、B、C, D are used for channel
selecting, but E is for parity format:
E=0 (without shorter) parity 8E1/8O1/9N1 (default)
E=1 (with shorter) parity 8N1
