Diversity High Power Wideband Radio Head (WRH-V)
A-2 044-05251 Rev A
Diversity
Figure A-2 illustrates the diversity block diagram configuration of the WRH-V. With diversity installed, there
are two paths on the UL instead of one. This requires an additional FON for the added receive path signal.
Signal flow is identical to the non-diversity version with the MCPA on the DL and LNAs on the UL providing
the additional amplification out of and into the WBA.
