RFM75W RF Transceiver Module RFM75W is a GFSK wireless rf transceiver module operating in the world wide ISM frequency band at 2400-2483.5 MHz. Burst mode transmission and up to 2Mbps air data rate make them suitable for applications requiring ultra low power consumption. The embedded packet processing engines enable their full operation with a very simple MCU as a radio system. Auto re-transmission and auto acknowledge give reliable link without any MCU interference. RFM75W operates in TDD mode, either as a transmitter or as a receiver. The RF channel frequency determines the center of the channel used by RFM75W. The frequency is set by the RF_CH register in register bank 0 according to the following formula: F0= 2400 RF_CH (MHz).
