This quad, power-doubled output amplifier features 40 db operational gain, up to 870 MHz expanded bandwidth, 110 analog channel capability and Bode equalization in a three-stage hybrid design. The high operational gain of the BT*/* permits the amplifier to be strategically placed within the system topology for distributing broadband telecommunications signals. "Tree and Branch" architectures are easily upgraded to Fiber to the Feeder (FTF) designs with the advanced features of the amplifier. ENHANCED GALLIUM ARSENIDE Optional Enhanced Gallium Arsenide (E-GaAs) hybrids are available in the STARLINE BT*/*. These E-GaAs hybrids replace the GaAs hybrids from the previous BT*/* platform. This second generation technology provides improved distortion performance in CTB and CSO over the standard GaAs technology. Compared to silicon and competing GaAs technology, E-GaAs distortion performance remains linear at significantly higher output levels. This higher output level allows the customer to maximize system performance and reduce system costs. We encourage our customers to contact their Motorola Account Representative to determine the optimal levels for their systems. All of Motorola Broadband Communication Sector s E- GaAs hybrids are designed and manufactured in our own facility and are not sold to competitors. HIGH GAIN The latest BT*/* also offers high gain for all model platforms as the standard model configuration. This 1 July 7 th, 2003

2 BT*/* STARLINE Broadband Telecommunications Amplifier allows the operator to hold existing amplifier locations during system upgrades thereby reducing system costs. ERGONOMICS: ENHANCED EASE OF USE Enhanced ergonomics add to the ease of use for the latest STARLINE series BT*/*. This ease of use is achieved by implementing taller attenuators as well as plastic shells and guides for forward and return equalizers, and cable simulators. All field- installed components are easily accessible through the chassis cover and can be installed and removed by a gloved hand without a tool. Block diagrams distinguishing forward and return paths by color are also printed on the chassis covers for easy reference of components. The ergonomic accessories are equivalent to the older non-accessories, with the addition of removable plastic guides and shells. All ergonomic and older nonergonomic accessories are completely backward/forward compatible. (Please see Backward/Forward Compatibility section). BKWARD/FORWARD COMPATIBILITY Forward Compatibility: The latest BT*/* units may use all ergonomic accessories, but it is also possible to use the older version EQ-*-*, BCS-*-*, SEE-*-*, and JXP- *A if desired. There is no need to remove the chassis cover to install the older accessories into the newer units. Backward Compatibility: The ergonomic accessories are the same as the previous accessories, except for the addition of the plastic guides and shells. See chart below for nomenclature. Therefore, the plastic guides and shells can be removed for use in older BT*/* versions. The reversible BT*/* electronics package is backward compatible with all previous BT* housings. The BT*/* amplifier is capable of carrying Amperes continuous through the input or output ports and up to 20 Amperes for 2 hours at +60 C. 60/90 VOLT POWERING The BT*/* is capable of 60 or 90 Vac powering. The 60/90 Volt power pack provides a regulated 24 Vdc output at 2.0 Amperes maximum over an ac input voltage range from 38 Vac through 90 Vac rms. The power supply also contains the additional feature of a two position (60V and 90V) selector that sets the startup voltage of the power supply. The BT*/* is shipped with the selector set for 60 Vac. There is no damage to the amplifier if the jumper is not changed. However, changing the jumper ensures that the dc supply does not turn on until the proper input voltage level is reached either 38 Vac or 55 Vac. This prevents excessive loading of the system power supply during turn-on after a system shutdown. The standard gas discharge tube surge arrestor can be replaced with the Fast Transfer Electronic Crowbar (FTEC-BTA) type surge suppressor for longer life over voltage protection. POWER FTOR CORRECTION The STARLINE Broadband Telecommunications Amplifier provides power factor correction in the power supply design. This feature lowers the current draw of the amplifier and improves the overall system power supply efficiency. DIRECTIOL COUPLER TEST POINTS Other features include directional coupler test points. The BT*/* is enclosed in the BTD-HSG which allows access to test points without opening the housing. FORWARD PATH The operational gain of the BT*/* is 40 db with 16 db return loss. Output level control is achieved through the use of an interstage Bode equalizer which compensates for coaxial cable attenuation changes due to temperature. Equalization may be controlled manually, with a thermal drive unit (Model TDU) or with a single pilot closed loop automatic drive unit (Model ADU-XXX/*). Both the TDU and the ADU boards are common to the STARLINE family of amplifiers. ADU's utilize Surface Acoustic Wave (SAW) filters for determining pilot frequency. This improves amplifier stability over temperature. To further ensure system flexibility and installation ease and maintenance, the amplifier is engineered for compatibility with standard accessories, such as attenuators, equalizers, ADUs and TDUs, return amplifiers, automotive fuses, BC style circuit breakers and FTEC/BTA crowbar circuits. 2

3 BT*/* STARLINE Broadband Telecommunications Amplifier The BT*/* uses modular diplex filters which can be changed for a different frequency split as required. The amplifier can be configured with S split filters for a 5-40 MHz return and a MHz forward band. E splits (5-30 MHz/ MHz), K splits (5-42 MHz/ MHz), J splits (5-55 MHz/ MHz), and A splits (5-65 MHz/ MHz) are also available. These same filters can be used for all Motorola RF distribution amplifiers. RETURN PATH Return amplifier kits can be ordered with high gain hybrids providing db minimum station gain. Return path equalizers from 0 to 12 db can be customer selected. Optional features include thermal compensation and ingress control switching. Thermal compensation comes in the form of a plug-in JXP- TH*B, which stabilizes gain and match over temperature extremes. Also available is Ingress Control Switching in 3 states. This pin diode attenuator circuit can lower levels by 6 db or by 38 db with a controlled slew rate for minimum bit errors. The 4-output BT*/* requires four ingress control switches when ordering this option (one switch required for each output port). The LIFELINE Broadband Telecommunications Amplifier transponder, model LL-BT-F3 is required to operate the Ingress Control Switch from a remote location. NETWORK MONITORING The optional status monitoring transponder, model LL- BT-F3, handles RF electronics performance, measurement control, and alarm generation. The LL- BT-F3 monitors line voltage, power supply voltage, internal temperature and features an optical tamper switch. The LL-BT-F3 is also used to control the optional ingress control switch and is frequency agile up to 120 MHz. CONFIGURATION To reduce customer costs and to accommodate customer specific needs, the STARLINE BT*/* can be fully configured in the Motorola factory at no additional cost to the customer.
