General Introduction
RFM12BP is a low costing ISM band transceiver module implemented with 500mW output power. It
works signal ranges from 433/868/915MHZ bands, The SPI interface is used to communicate with
microcontroller for parameter setting.
Features:
• High output power with 500mW
• High input sensitivity with -117dBm
• Low costing, high performance and price ratio
• PLL and zero IF technology

• High data rate (up to 115.2 kbps with internal
demodulator，with external RC filter highest data
rate is 256 kbps)
• 50 OHM antenna input/output
• Programmable TX power
• Programmable TX frequency deviation (from 15
to 240 KHz)
• Programmable receiver bandwidth (from 67 to
400 kHz)
• Analog and digital signal strength indicator
(ARSSI/DRSSI)
