Overview of RF Modules for Prism Remote Units
HDM RF Modules
High-Density Module (HDM) RF Modules (
Figure 3
) are designed to provide the ability to deploy either a two
20W Multiple Input Multiple Output (MIMO) paths of the same band, known as a MIMO RF Module; two 20W
Single Input Single Output (SISO) with two different bands, known as dual RF Module; or a single 40W Single
Input Single Output (SISO) RF Module within a single-bay of a PRU.
Figure 3.
HDM RF Modules
An HDM RF Module does the following:
•
interfaces with one Host DART-either Classic or SuperDART, or one CDIU
•
supports two non-contiguous RF slices up to 35 MHz total bandwidth in a Dual or MIMO configuration
•
supports full bandwidth in a SISO configuration, up to 75 MHz
•
supports 20W per band/Path in a Dual/MIMO RF Module
•
supports up to 40W RF output power in a SISO RF Module.
The components of a PRU HDM RF Module are dependent on the module type, as listed in
Table 12
.
