1 Bill of Materials and Implementation of the Transceiver Base Station Board ATAB5823/24-x-B The ATA5823/24 is part of Atmel s RF multichannel transceiver family dedicated to unlicensed frequency bands. This document describes the bill of materials (BOM) required to operate the ATA5823/24, allowing use of this RF transceiver in the popular ISM bands 35/433/868 MHz. Most of the components values are the same regardless of the frequency bands; only the matching of the antenna and the quartz crystal should take into account the frequency that is targeted. This BOM relates to the implementation of our demo boards. The two-layer layout that is provided is recommended. Nevertheless, it is possible to use a different layout, which might require some minor change of values for optimal use. Transceiver Base Station Board ATAB5823-x-B/ ATAB5824-x-B Application Note. Schematic and Layout The schematic of the demo board is illustrated in Figure - on page 2, and the layout is shown in Figure -2 on page 3, Figure -3 on page 3, Figure -4 on page 4 and Figure -5 on page 4.

5 ATAB5823/24-x-B 2. Board Versions and Bill of Material The transceiver base station board is available for 35 MHz, MHz and MHz in high power mode, that is, with an RF output power of approximately 0 dbm at 50Ω. The board ordering numbers for the different frequency versions are given in Table 2-. Table 2-. Board Versions RF Frequency Board Ordering Number 35 MHz ATAB B MHz ATAB B MHz ATAB B Each application operating in a given frequency band must be set to correspond to Table 2-2 to get the best performance from the transceiver.
