with external diplexer: due to an high number of shifters the diplexer is external for
the flexibility of the shifter customization (5.8 GHz, L6, U6, 7 GHZ, 8 GHz and 10,5
GHz), where MPT-HC V2/MPT-XP/9558HC is composed by two independent units:
the BRANCHING assembly (containing the diplexer) and the RF TRANSCEIVER
assembly (containing the RF section); each of this type of MPT-HC V2/MPT-XP/
9558HC is identified by two Logistical Items, one for the branching assembly and
another for the RF transceiver assembly. To read the branching assembly
identification label it is necessary to separate the branching assembly from the RF
transceiver assembly.

For 5.8 GHz (external diplexer) in MPR-A, the 9558HC polarization is determined by the
rotation of the 9558HC (1+0 configuration).
For 6, 7, and 8 GHz (external diplexer), the MPT-HC V2/MPT-XP polarization is determined
by the rotation of the MPT-HC V2/MPT-XP (1+0 configuration).
For 6, and 11 to 38 GHz (embedded diplexer), the MPT-HC V2 polarization is determined by
the rotation of the polarization rotator fitted in the antenna port of the MPT-HC V2 (1+0
configuration).
Two mechanical solutions are adopted:
•
with an embedded diplexer for cost optimisation (6, and 11 to 38 GHz), shown in
MPT-HC V2/MPT-XP/9558HC block
MPT-HC V2 cabinet; this type of MPT-HC V2 is identified by one Logistical Item
only;
•
with an external diplexer: due to a high number of shifters, the diplexer is external
for the flexibility of the shifter customization (5.8, 6, 7, 8, and 10.5 GHz for MPR-
E, 5.8, 6, 7, and 8 GHz for MPR-A), where the MPT-HC V2/MPT-XP is composed
of two independent units: the EXTERNAL DIPLEXER assembly (containing the
diplexer) and the RF TRANSCEIVER assembly (containing the RF section); each of

MPR-e
