1.5 External Passive Module (EPM)
The external passive module (EPM) is required when in installations with an existing MA1000/MA2000 remote unit (e.g.
MA2000 QX). The EPM is used to combine up to four low band output wideband signals with the high band HX 2.5
GHz TDD output signal. The module includes a 1:4 splitter for the high band (i.e. 2.5 GHz TDD) and four internal
diplexers that combine the 2.5 GHz TDD signal with the wideband signal received from the MA1000/MA2000 remote.
The EPM interfaces to the HX 2.5 GHz TDD and to the service combiner unit (SCU) of the MA1000/MA2000 remote.
