WRH-V
The WRH-V has a configuration similar to the standard WRH with the exception of a the MCPA
that boosts the ouput DL signal from the PA. The MCPA is located at positions 3 and 4 in the
cabinet. The MCPA requires an additional heat sink and is attached to the MCPA PCBA. A
WRH-V 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 1-5 and a block diagram is located in
Appendix A.
