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.
