Description
The RFM42/43 is low cost ISM transmitter module and offers advanced radio features including continuous
frequency coverage from 240–930 MHz with adjustable power output levels of –8 to +13 dBm on the RFM43 and
+8 to +17 dBm on the RFM42. Power adjustments are made in 3 dB steps. The RFM42‘s Industry leading +17
dBm output power ensures extended range and improved link performance.
Additional system features such as an automatic wake-up timer, low battery detector, 64 byte TX FIFO, and
automatic packet handling reduce overall current consumption and allow the use of lower-cost system MCUs. An
integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs further reduce overall
system cost and size.
The direct digital transmit modulation and automatic PA power ramping ensure precise transmit modulation and
reduced spectral spreading ensuring compliance with FCC and ETSI regulations.
