Split Mount Configuration and Branching Network

• Outdoor Circulator Block OCB – The Tx and the Rx path
circulate together to the main OCB port. When chaining
multiple OCBs, each Tx signal is chained to the OCB Rx
signal and so on (uses S-bend section). For more details,
refer to 1500HP/RFU-HP OCBs
• Indoor Circulator Block ICB – All the Tx signals are
chained together to one Tx port (at the ICC) and all the Rx
signals are chained together to one Rx port (at the ICC). The
ICC circulates all the Tx and the Rx signals to one antenna
port.

New OCB – Outdoor Circulator Block
The OCB has the following main purposes:
1. Hosts the circulators and the attached filters.
2. Chain and accumulate radio signal ( multiple carriers )
3. Routes the RF through the filters and circulators.
4. Allows RFU connection to the Main and Diversity antennas.

New OCB Components

• RF Filters - are used for specific frequency channels and Tx/Rx separation. The filters are attached to the OCB,
and each RFU contains one Rx and one Tx filter. In a Space Diversity using IF combining configuration, each RFU
contains two Rx filters (which combine the IF signals) and one Tx filter. The filters can be replaced without
removing the OCB. The RF filter is installed with every configuration.
• DCB - Diversity Circulator Block An external block which is added in Space Diversity configurations. DCB is
connected to the diversity port and chains two OCBs.
• Coupler Kit is used for 1+1 Hot Standby configurations. (loss 1.6 /6dB)
• Symmetrical Coupler Kit is used for: (loss of 3/3 dB) • When chaining adjacent channels (only 28/30 MHz) • 1+1
Hot Standby configurations with a symmetrical loss of 3dB in each direction Note: CPLRs loss tolerance is ±0.7
dB
• U Bend The U Bend connects the chained DCB (Diversity Circulator Block) in N+1/N+0 configurations.
• S Bend The S Bend connects the chained OCB (Outdoor Circulator Block) in N+1/N+0 configurations.
• Pole Mount Kit The Pole Mount Kit is used to fasten up to five OCBs and the RFUs to the pole. The kit enables
fast and easy installation.
