RFM23BP是高度集成，成本低，433/470/868/915MHZ无线收发模块。低接收灵敏度（-120dBm）,再加上+30 dBm的输出功率，确保延长范围和提高链路性能。内置天线多样性和支持跳频以进一步扩大范围和提高性能。
RFM23BP are highly integrated, low cost,433/470/868/915MHZ wireless ISM transceivers module. The low receive sensitivity(–120dBm) coupled with industry leading +30dBm output power ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance. Additional system 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 and allow the use of lower-cost system MCUs. An integrated temperature sensor, general purpose ADC, poweron-reset (POR), and GPIOs further reduce overall system cost and size.

The RFM23BP digital receive archit ecture features a high-performance ADC and DSP based modem which performs demodulation, filtering, and packet handling for increased flexibility and performance. 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. An easy-to-use calculator is provided to quickly configure the radio settings, simplifying customer's system design and reducing time to market.
