Single-Bay Prism Remote Unit Dual-Bay Prism Remote Unit Tri-Bay Prism Remote Unit Quad-Bay Prism Remote Unit Figure 1. Prism Remote Units (PRUs) Depending on the Prism Remote Unit model, a PRU enclosure can have from one to four RF Module bays and can support up to four RF Modules, as indicated by the model name.
RF Module Digital/Analog Radio Transceivers Each RF Module can support any of the following Digital/Analog Radio Transceiver (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 and Rx Boards (HDM). Each RF Module will have up to two 6-timeslot DARTs or one 12-timeslot DART per RF Module.
Table 5.
RF Module Types The Remote Unit RF Modules are available in the following formats, and as described in the following sections: • “Single- and Dual-Bay RF Modules with Classic or SuperDARTs” on page 9 • “HDM RF Modules” on page 10 • “Legacy Dual-Bay 40W RF Modules” on page 11. Single- and Dual-Bay RF Modules with Classic or SuperDARTs Figure 2 shows examples of Single- and Dual-Bay RF Modules, both of which have two DARTs.
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.
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 that comprises – one Low Noise Amplifier (LNA) – one Power Detector (PD) • 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.

Linear Power Amplifiers The Linear Power Amplifier (LPA) is a high quality broadband RF amplifier used for achieving Prism product-rated power for the Remote Unit 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 13 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 Remote Unit 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.

UNDERSTANDING 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 that older labeling schemes used “PRI” and “DIV”.
Table 11.
RF Module Cables and Supported Bay Installations for Legacy Dual-Bay 40W RF Modules The cables and connectors have corresponding labels as shown in Table 12 for Legacy Dual-Bay 40W RF Modules. Table 12 also shows which RF Module type can be installed in which PRU bay(s) when a 40W Dual-Bay RF Module is part of the RF Module mix in a PRU chassis. The Single-Bay chassis is not included in Table 12.
INSTALL THE RF MODULE(S) The following sections guide you through the installation of an RF Module into a Remote Unit 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 Remote Unit enclosure. 2 Remove release liners, if present, from the thermal pads on the RF Module prior to installing the module into the Remote Unit 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 11 on page 19.) Remove the shelf as appropriate for the RF Module: • When installing in the A and B Bays, remove the Module B Bay Shelf. • When installing in the C and D Bays, remove Module D 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.
