For single wideband operation the cabinet is equipped with a WBA in position 1 for both DL and UL
paths and an associated PA in position 2 for DL signal amplification. For dual band operation another
set of PCBAs can be used in positions 3 and 4. The WRH has a FON for uplink transmission via fiber
optics. A high cover can be equipped as well providing up to four bands. PCBA positions are illustrated
in the Figure 1-6 and a block diagram is located in Appendix A.
The booster option boosts the output DL signal from the PA. The BA is located at position 3 in the
cabinet. A booster can only be equipped for one band in the cabinet and an additional band in a high
cover. PCBA positions are illustrated in the Figure 1-7 and a block diagram is located in Appendix A.
