2 OVERVIEW

LPZigBee module mainly consists of three sections: the microcontroller
ATXmega256D3 and periphery, the radio transceiver AT86RF231 and the RF front­end with power amplifier and low-pass filtering.

The ATXmega256D3 controls the AT86RF231 radio transceiver and serves as an
SPI master. The radio transceiver handles all actions concerning RF
modulation/demodulation, signal processing, frame reception and transmission. MAC
hardware acceleration functions are implemented in the radio transceiver, too.
Further information about the radio transceiver and the microcontroller are available
in the appropriate datasheets, refer to 1.5 references.
The RF front-end incorporates signal amplification and filtering of the transmit signal.
The degree of filtering depends on operating conditions as well as regional aspects.
Switching between reception and transmission is directly controlled by the radio
transceiver.
