2 OVERVIEW

LPZigBee module mainly consists of two sections: The System-on-Chip (EM357) and
the RF front-end (SE2432L) with power amplifier and low-pass filtering.

The EM357 includes radio transceiver and microcontroller. 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.
