Overview of Prism Remote Units O V ER V I E W OF PRISM REMOTE UNITS FlexWave PRUs control RF emissions, interface with the FlexWave Prism Host Unit II and perform the optical to electrical conversion for transport to the antennas. The PRU is an environmentally-sealed unit designed for outdoor use that houses the electronic assemblies such as the Digital/Analog Radio Transceiver (DART) board and the Power Amplifier, and seals out dirt and moisture.

Overview of Prism Remote Units PORTS AND CONNECTORS Make sure you refer to the section that describes the PRU deployed in your installation. "Bottom of an AC-Powered Quad-Bay PRU” on page 8 and "DC-Powered Quad-Bay PRU” on page 9 shows the differences between an AC-powered and a DC-powered PRU. The differences will be the same for Single-Bay, Dual-Bay, and Tri-Bay chassis.

Overview of Prism Remote Units Remote Unit Status LED This section illustrates the Status LED on a Quad-Bay PRU. The Status LED for the Single-Bay, Dual-Bay, and Tri-Bay PRUs is in the same location and functions the same as the Status LED for the Quad-Bay PRU. The Remote Unit has a single red Status LED that is located on the bottom of the chassis.

Overview of RF Modules for Prism Remote Units O V ER V I E W OF RF MODULES FOR PRISM REMOTE UNITS Dependent 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. That is, the Single-Bay PRU has one RF Module bay and can only support one RF Module, and the Quad-Bay PRU has four RF Module bays and can support up to four RF Modules.
Overview of RF Modules for Prism Remote Units Prism supports the DART Module types listed below. • Classic DARTs are 6-timeslot DARTs that support up to 35 MHz contiguous bandwidth (see Table 9). • Single SuperDARTs are 6-timeslot DARTs that support two non-contiguous bands in the entire frequency range of the DART, but cannot exceed 35 MHz total RF bandwidth (see Table 10).

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.
Overview of RF Modules for Prism Remote Units 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.

Overview of RF Modules for Prism Remote Units 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 13 for Single-Card, Dual-Card, and HDM RF Modules and Table 14 on page 19 for Legacy Dual-Bay 40W RF Modules. The LPA is housed within the RF Module, and is not field serviceable. Table 13.
Overview of RF Modules for Prism Remote Units 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.

Configuring the System with RF UNDERSTANDING RF CABLE RULES CAUTION! To avoid the risk of equipment damage, ensure that the AC/DC Power switch to the PRU chassis and all RF Module DC power switches are in their OFF position before connecting or disconnecting coaxial cables; otherwise equipment damage may occur. • • • 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.
