Description
The RF42/43 offers advanced radio features including continuous frequency coverage from 240–930 MHz with
adjustable power output levels of –8 to +13 dBm on the RF43 and +11 to +20 dBm on the RF42. Power
adjustments are made in 3 dB steps. The RF42/43‘s high level of integration offers reduced BOM cost while
simplifying the overall system design. The RF42‘s Industry leading +20 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.
