the placeholders are reserved to support separated inputs of the HC-MMPA.
The WTR1625(L) + WFR1620 RF (APAC Carrier Aggregation) Preliminary Reference Schematic
(80-NA805-44) and the WTR1625(L) RF APAC Preliminary Reference Schematic (80-NA805-47) MTP are
designed to support the shorted-pins configuration. These are design preferences and based on current
results. Both implementations are OK with ACPM-7600 rev. A4A

It is recommended that customers verify with the HC-MMPA vendors whether the input pins can be shorted.
