Wireless RF Sub-GHz Transceiver Module RFM23BW: HopeRF's RFM23BW are highly integrated, low cost,433/868/915MHZ programmable wireless ISM RF transceiver module. The low receive sensitivity(?121dBm) coupled with industry leading +20dBm output power ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping
Additional features such as an automatic wake-up timer, low battery detector, 64 byte TX/RX FIFOs, automatic packet handling, and preamble detection reduce overall current consumption An integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs
The RFM23B's digital receive architecture features a high-performance ADC and DSP based modem which performs demodulation, filtering, and packet handling. 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.
