Connecting Cables in a Single ‐ Slot RF Module Installation
1
Position the cables so that they are under the right edge of the RF Module, pointing up.
2
Follow the rules listed in “Understanding the RF Module Cables” on page 15 .
3
Working from the bottom connector up, connect the RF Module cables, as follows:
a
Connect the MOD N TX1/RX1 cable to the RF Module.
i
If a TX1/RX1 RF Module connection is available, insert the N‐Style Plug of the MOD N
TX1/RX1 cable into the TX1/RX1 N‐Style Jack of the RF Module. If RF Module
connection is not available, constrain the MOD N TX1/RX1 cable to accompanying
cables using a tie wrap so it cannot be pinched or prevent the PRU door from closing.
ii
Turn the coupling nut of the plug clockwise to thread onto the jack and finger‐tighten.
iii
Torque coupling nut to 8 +/‐ 1 in‐lbs to ensure full connection.
NOTE: Insufficient torque applied to RF Module connections can result in elevated insertion/return loss
and higher than normal VSWR reported by the system.
b
Connect the MOD N TX0/RX0 cable to the RF Module.
i
Insert the N‐Style Plug of the MOD N TX0/RX0 cable into the TX0/RX0 N‐Style Jack of
the RF Module.
ii
Turn the coupling nut of the plug clockwise to thread onto the jack and finger‐tighten.
iii
Torque coupling nut to 8 +/‐ 1 in‐lbs to ensure full connection.
NOTE: Insufficient torque applied to RF Module connections can result in elevated insertion/return loss
and higher than normal VSWR reported by the system.
c
Connect the LVDS Cables to the RF Module.
i
Connect the MOD N DIV LVDS Cable to the DIV receptacle of the RF Module by
inserting and sliding in until fully seated.
NOTE: Always connect the Diversity LVDS Cable with the RF Module.
ii
Connect the MOD N PRIM LVDS Cable to the PRIM connector, following the same steps
as above.
NOTE: Full insertion can be recognized by an audible click as the LVDS Cable Connector locks into the RF
Module Receptacle. This can be verified by lightly pulling back on the LVDS connector while
making sure not to depress the release trigger. When fully inserted, the cable should not be able
to be removed from the receptacle.
d
Connect the Power Cable Connector to the PWR receptacle of the RF Module by inserting
and sliding in until fully seated.
NOTE: Full insertion can be recognized by an audible click as the Power Cable Connector locks into the
RF Module Receptacle. This can be verified by lightly pulling back on the Power Cable Connector
while making sure not to depress the release triggers on the ends of the connector. When fully
inserted, the cable should not be able to be removed from the receptacle.
