RadioBlade Shelf (RBS)
The RadioBlade Shelf (RBS) houses the iDEN 2-port RadioBlade transceivers, the RadioBlade
transceiver “backplane”, and RF combiner and splitter assemblies. The whole assembly is
housed in a pullout shelf to facilitate field replacement of the RadioBlade transceivers.
transceiver “backplane”, and RF combiner and splitter assemblies. The whole assembly is
housed in a pullout shelf to facilitate field replacement of the RadioBlade transceivers.
The RBS is divided logically into three sets of eight slots. Each set of slots is referred to as a
group—A, B, and C—numbered from left to right when facing the front of the unit. The groups
share redundant DC-DC converters. The slot connectors on the RBS provide the control and data
interface to each RadioBlade transceiver. Each group interfaces with the AIC via a separate
100BaseT Ethernet connection. In addition, a serial console port and status LEDs for each group
are routed to the front panel of the RBS.

RF combining is also accomplished on a per group basis. Integrated into the RBS are 1:8 power
splitters for the Rx path and 8:1 power combiners for the Tx path.
