The low receive sensitivity(- 121d Bm) coupled with industry leading +20d Bm 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 RFM22B/23B’s digital receive architecture features a high-performance ADC and DSP based modem which performs demodulation,...
