Connecting Cables in a Single‐Bay 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
.
3
Connect the RF Module cables, in the following order:
a
a
Connect the MOD N TX0/RX0 cable to the RF Module.
i
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.
higher than normal VSWR reported by the system.
b
Connect the MOD N TX1/RX1 cable to the RF Module.
i
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.

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.
