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.
Linear Power Amplifiers The Linear Power Amplifier (LPA) is a high quality broadband RF amplifier used for achieving Prism product‐rated power for the PRU Tx forward path RF. The PAs are pass‐band specific, with the maximum composite Tx power levels listed in Table 8 for Single‐Card, Dual‐Card, and HDM RF Modules and Table 9 on page 12 for Legacy Dual‐Bay 40W RF Modules. The LPA is housed within the RF Module, and is not field serviceable. Table 8.
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).
UNDERSTANDING THE RF MODULE CABLES Before you install the RF Module cables, familiarize yourself with the rules that pertain to these cables, as defined in the following sections. Always provided at each RF Module shelf are five cables: • two High‐Speed Data Cables, which in this document are referred to as LVDS (Low‐Voltage Differential Signaling) cables • two RF Cables (TX0/RX0) and (TX1/RX1) • one Power (PWR) Cable.
• RF cables are hand‐formable; however, cables must adhere to a minimum bend radius of 1‐inch from the outlet of the integrated cable guide to the respective N‐Style RF connection on the RF Module. RF Module Cables for Single‐Card, Dual‐Card, and HDM RF Modules The RF cable and connector labels also correspond to the RF Module bays in the PRU chassis, where MOD A is the bottom bay and MOD D is the top bay.
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 11 on page 16 for Legacy Dual‐Bay 40W RF Modules. Table 11.
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. Quad-Bay Remote Unit with Single-Card RF Modules DART 7 Bay D DART 8 DART 5 Bay C DART 6 DART 3 Bay B DART 4 DART 1 Bay A DART 2 SeRF Module Figure 7.

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 a Prism Remote Unit 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 Prism Remote Unit or any of its components.
Remove Release Liners from the RF Module NOTE: Release Liners are present on front and back of new modules. 1 Open the PRU enclosure. 2 Remove release liners, if present, from the thermal pads on the RF Module prior to installing the module into the PRU chassis. CAUTION! The thermal pads are very sensitive to mishandling—do not nick, scratch, or ding them.
For HDM RF Modules, the thermal pads are located as listed below and as shown in Figure 10. • one pad for each Rx and Tx board • one large pad over the DPM • one for each Power Amplifier (PA), which is on the bottom of the HDM RF Module. DPM Thermal Pad Rx B Thermal Pad Rx A Thermal Pad Tx A Thermal Pad 2.9796 in Tx B Thermal Pad NOTE: Tx and Rx cards are paired: Tx A ony pairs with Rx A and Tx B only pairs with Rx B. 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 10 on page 15.) 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. NOTE: 2 Always install RF Modules from the bottom up. Do not skip a bay, as this provides more efficient heat dissipation.
