Description
HopeRF's RFM22B/23B are highly integrated, low cost,433/868/915MHZ
wireless ISM transceivers 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 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, power-
on-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, 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.
