Diversity
Figure A-2 illustrates the diversity block diagram configuration of the WRH. 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.
