HopeRF's RFM42B/43B are highly integrated, low cost,433/868/915MHZ
wireless ISM transmitters module.
The RFM42B/43B offers advanced radio features including adjustable power
output levels of –8 to +13dBm on the RFM43B and +1 to +20dBm
on the RFM42B.Power adjustments are made in 3dB steps.The RFM42B/43B's
high level of integration offers reduced BOM cost while simplifying the overall
system design. The RFM42B’s Industry leading +20dBm 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 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.
