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.  
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.
