BSR Physical Sections The BSR (Base Station Rack) is a complete unit, assembled of three sections: a bottom section, a middle section, and a top section. The three sections are detailed below. Base Station Bottom Section The bottom section of the BSR houses the PAs (power amplifiers), the UPS (Uninterruptible Power Supply), and the Upconverters. For a one-sector installation, install the single PA in the PA 3 slot. For a two-sector installation, install the two PAs in the PA 3 and PA 2 slots.
Base Station Middle Section The middle section of the BSR houses the WMTS (V3000), Remote Control Unit, Upstream splitter tray and customer added backhaul interface. The three Monitoring Modem Units (MMU) are located on the back side of the middle section, behind the WMTS. For a one-sector installation, install the MMU in the left-most slot. For a two-sector installation, install the MMUs in the two left-most slots.
Base Station Top Section The top section of the BSR houses the Diplexer module (including the TX/RX Diplexer and the directional couplers), the upstream LNA module (including upstream LNA, Band Pass Filter and splitters), the upstream Downconverter modules (including Downconverter and splitter), ground-bus to facility point, and electric power to facility point. The antenna connection ports are located on the top of the rack. The Diplexer, LNA, and Downconverter each consist of three units.
LNA Module, described on page 3. Downconverter, described on page 3. Test Points, described on page 3. Monitoring Modems, described on page 3. The following sections describe each component in detail.

the chassis. The modulator and hex demodulator cards are inserted in the rear of the chassis. The ON/OFF power switch and the fuse are located in the rear of the power supply. The rear panel of the chassis is illustrated in Figure 7, and the front panel in Figure 8.
Figure 8 shows the WMTS chassis with (from left to right) Upstream module, Downstream module, Control and Forward card, Host card, and Power Supplies.
Upconverter The digital QAM Upconverter includes four independent single IF upconverter modules. Three of the upconverter modules are used, each for a sector. The fourth upconverter serves as a spare. The unit uses a common power supply and control module to manage all the upconverters. An easy to read back-lit LCD is used to display all the module information. The unit features an advanced menu system, which provides for easy programming using the push-button navigation switches on the unit’s front panel.
Figure 9: Power Amplifier – Front and Rear Diplexer The Diplexer separates the TX/RX signal being transmitted to/from the antenna. The Diplexer supports a very high TX to RX signal separation. LNA Module The LNA module receives the upstream received signal from the Diplexer, amplifies it, and delivers it to the Downconverter. The LNA module includes two Low Noise Amplifiers in series. A narrow band BPF (band pass filter) is placed between the amplifiers to improve receive signal filtering.
