OVERVIEW OF RF MODULES FOR PRISM REMOTE UNITS Figure 1 illustrates the Prism Remote Unit (PRU), which controls RF emissions, interfaces with the FlexWave Prism Host Unit. Single-Bay Dual-Bay Tri-Bay Quad-Bay Prism Remote Unit Prism Remote Unit Prism Remote Unit Prism Remote Unit Figure 1. Prism Remote Units (PRUs) The PRU has from one to four RF Module bays, depending on the PRU model. That is, the Single‐Bay PRU has one RF Module bay, and the Quad‐Bay PRU has four RF Module bays.
RF Module DARTs Each RF Module can support any of the following DART combinations: • one Classic DART or one Single SuperDART • two Classic DARTs (i.e., the 6.5W 800/900 ESMR Module, Non‐Diversity, Classic) • two Classic DARTs—Diversity • two Single SuperDARTs—Diversity • one Dual SuperDART • one or two sets of Tx or Rx Boards (HDM). Each RF Module will have up to two 6‐timeslot DARTs or one 12‐timeslot DART per RF Module.

HDM RF Modules HDM RF Modules (Figure 3) are designed to provide the ability to deploy either a 20W Dual /Multiple Input multiple Output (MIMO) RF Module (where dual equals two bands) or a 40W Single Input Single Output (SISO) RF Module within a single‐bay of a PRU.
Legacy Dual‐Bay 40W RF Modules The Legacy Dual‐Bay 40W RF Module (Figure 5) is designed for AWS and PCS frequencies and is supported only by Classic DARTs. The Legacy Dual‐Bay 40W RF Module comprises: • one Classic DART • one Duplexer • two Power Amplifiers (PAs) • one Remote DART Interface (RDI) board. NOTE: This manual describes how to install the PCS 1900 and AWS 2100 Non‐Diversity RF Modules. Figure 4.
RF MODULE COMPONENTS Figure 5 shows typical RF Module components, using the Single‐Bay RF Module as an example. DARTs Mounting latch Mounting hook LNA (inside the Duplexer cavitiy) Power Amplifier (PA) Duplexer NOTE: The RDI is internal to the RF Module and is therefore not shown. Figure 5. Single‐Bay RF Module Components Figure 6 shows the components of an HDM RF Module. DPM Tx and Rx Cards Duplexers Power Amplifier Mounting hook Mounting latch Figure 6.
Duplexer and Low Noise Amplifier The RF Module provides the PRU with an internal Duplexer that is optimized to provide the desired RF band‐pass filtering and in‐band equipment isolation between FWD and REV paths. The Duplexer provides the filtering necessary to the transmit and receive paths to and from the connected antenna. The Duplexer for the Single‐ and Dual‐Bay RF Modules and the Legacy Dual‐Bay 40W RF Modules contains up to two REV path Low Noise Amplifiers (LNA for PRI and/or SEC reverse paths).
Digital Processing Module The Digital Processing Module (DPM) is found only in the HDM RF Modules. The DPM provides the primary processing and logic functions for the HDM RF Module. It also provides the primary power interface for the HDM RF Module, and conversion of the native 28 Vdc voltage to lower voltages as necessary for functionality. The DPM has a Transmit (Tx) Board and a Receive (Rx) Board: • Tx Board—provides band specific filtering for the intended Transmit path.
RF Cable Rules When installing a Diversity, MIMO or Dual‐Band RF Module, both RF cables labeled MOD N TX0/RX0 and MOD N TX1/RX1 shall be connected to the N‐Style connections of the RF Module” • NOTE: Older labeling schemes used “PRI” and “DIV”.
RF Module Cables for Dual‐Bay Installations For Dual‐Bay installations, the RF cables and connectors are labeled as MOD N TX0/RX0 and MOD N TX1/RX1, where N refers to the top bay of the double‐bay installation. For example, for a Dual‐Bay installation in a Quad‐Bay chassis, the RF cables and connectors are labeled as MOD C TX0/RX0 and MOD C TX1/RX1. The cables and connectors have corresponding labels as shown in Table 10 on page 14 for Legacy Dual‐Bay 40W RF Modules. Table 10.
RF Group Assignments for PRUs A PRU comprises from one to four RF Module bays. Figure 7 illustrates the numbering of RF Module bays and DARTs.

Table 11 lists how the FlexWave Prism EMS references the RF group assignments and corresponding components of each RF Module. Table 11.
The Legacy Dual‐Bay 40W RF Module occupies two bays in a PRU. Figure 8 shows the main components in a PRU enclosure, with a Legacy 40W RF Module occupying Bays A and B. The controlling DART will always be in the upper bay (B or D), and the second LPA is always in the lower bay (A or C).
INSTALL THE RF MODULE(S) The following sections guide you through the installation of an RF Module into a PRU chassis. The process to install the four different types of RF Modules is basically the same; however, differences are noted and should be followed. NOTE: In the following steps, the RF cables and connectors are referred to as MOD N TX0/RX0 and as MOD N TX1/RX1 where N equals A, B, C, or D.
Guard against Damage from Electro‐Static Discharge CAUTION! Electro‐Static Discharge (ESD) can damage electronic components. To prevent ESD damage, always wear an ESD wrist strap when working with the PRU or when handling any of its components—including the RF Modules. Connect the ground wire on the ESD wrist strap to an earth ground source before touching the PRU or any of its components. Wear the wrist strap the entire time that you work with the PRU and its components.
One thermal pad for RF Power Combiner One thermal pad for Vector Modulator One thermal pad for each DART One thermal pad for each DART One thermal pad for the RDI One large thermal pad on each PA (bottom of the LPA) Figure 9. Thermal Pads on a Legacy Dual‐Bay 40W RF Module For HDM RF Modules, the thermal pads are located as listed below and as shown in Figure 10.
Dual‐Bay Modules Only—Remove the Module Bay Shelf 1 FOR DUAL‐BAY RF MODULES ONLY. If you are installing a Dual‐Bay RF Module, you must remove a module bay shelf from the PRU chassis to accommodate the module’s size. (For further information, see Table 9 on page 13.) Remove the shelf as appropriate for the RF Module: • For a Legacy Dual‐Bay 40W RF Module, when installing in the A and B Bays, remove the Module B Bay Shelf.
Install the RF Module into the Prism Remote Chassis 1 Hold the RF Module so that the DART card(s) face away from the PRU and the Mounting Hook is toward the Receiving flange on the PRU chassis. Always install RF Modules from the bottom up. Do not skip a bay, as this provides more efficient heat dissipation.
