BSA PCBA
Table 2-4 lists the connectors and connections for the BSA PCABA. Coaxial connector P101
is the input port and coaxial connector P301 is the output port. The signal from this port is fed
to the PA input port P4. The PA output port P5 is connected to the duplex filter of the same
path direction.
Table 2-4 BSA PCBA Connections
PA PCBA
Coaxial connector P4 is the input port and coaxial connector P5 is the output port. PA output
port P5 is connected to the DPX of the same path direction.
BA PCBA
Table 2-5 lists the connectors and connections for the BA PCABA. Coaxial connector P3 is
the input port (fed by the DL PA) and coaxial connector P4 is the output port. The signal from
this output is fed, via the DL DPX and DC, to the DL antenna.
