1.0 Introduction
The MRF450 radio module is an RF modem. The module consists of a Silicon Labs RF
transceiver coupled with a 32-bit Atmel ARM processor. The module is intended to be
integrated into Cervis product, providing RF connectivity while hiding the complexity of RF
communications and link management.
The radio is designed to operate in the 450 – 470 MHz band with a maximum output power of
less than 15 dBm. The radio can operate on any center frequency in the band with a resolution
of 1 kHz. The center frequency is fixed for the duration of operation. The radio utilizes 2(G)FSK
modulation in a 12.5 kHz channel bandwidth.
