reduced BOM cost while simplifying the overall  
Industry leading +20dBm output power ensures  
link performance.  
high level of integration offers  
system design. The RFM42B’s  
extended range and improved  
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 global regulations including FCC,ETSI regulations.  
An easy-to-use calculator is provided to quickly configure the radio settings,  
simplifying customer's system design and reducing time to market.
