UNIVERSAL ISM BAND FSK TRANSCEIVER MODULE

WITH 500mW OUTPUT POWER

RFM12BP

（the purpose of this spec covers mainly for the physical characteristic of the module, for register

configure and its related command info please refer to RF12B datasheet）

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

• Automatic frequency control (AFC)

• Data quality detection (DQD)

• Internal data filtering and clock recovery

• RX synchron pattern recognition

• SPI compatible serial control interface

• Clock and reset signal output for external MCU

use

• Fast PLL lock time

• High resolution PLL with 2.5 KHz step

• High data rate (up to 115.2 kbps with internal

demodulator，with external RC filter highest data

rate is 256 kbps)

• 16 bit RX Data FIFO

• Two 8 bit TX data registers

• 50 OHM antenna input/output

• Programmable TX power

• Wakeup timer

• 2.2V – 3.8V power supply for FSK IC, 12V power

supply for power amplifier

• Programmable TX frequency deviation (from 15

to 240 KHz)

• Standby current less than 0.3uA

• Supports very short packets (down to 3 bytes)

• Programmable receiver bandwidth (from 67 to

400 kHz)

• Analog and digital signal strength indicator

(ARSSI/DRSSI)
