This single output amplifier offers high gain, high output levels, improved ergonomics, improved distortion performance, six diplex filter options, 16 db return loss for E-GaAs, and Bode equalization. The also allows optional advanced features such as ingress control switching and status monitoring. ENHANCED GALLIUM ARSENIDE Optional Enhanced Gallium Arsenide (E-GaAs) hybrids are now available in the STARLINE 2000 BLE. These E-GaAs hybrids now replace the GaAs hybrids from the previous BLE 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 BCS s GaAs and E-GaAs hybrids are designed and manufactured in our own facility and are not sold to competitors. HIGH GAIN The latest BLE also offers a high gain version as the standard model configuration by combining the latest silicon and GaAs hybrids in the 870 MHz platform. This allows the operator to hold existing amplifier locations during system upgrades thereby reducing system costs. 1

2 ERGONOMICS: ENHANCED EASE OF USE Enhanced ergonomics add to the ease of use for the latest STARLINE 2000 series. This ease of use is achieved by implementing taller attenuators as well as plastic shells and guides for forward and return equalizers, cable simulators and response correction boards. 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 new ergonomic accessories are equivalent to the previous accessories, with the addition of removable plastic guides and shells. The taller attenuator is simply a taller version of the previous part allowing the part to be accessible through the chassis cover. All new and former accessories are backward/forward compatible except the taller attenuator (please see Backward/Forward Compatibility section). BACKWARD/FORWARD COMPATIBILITY Forward Compatibility: The latest BLE units may use all ergonomic accessories, but it is also possible to use the older version EQ-*-*, BCS-*-*, SEE-*-*, and JXP- *A if desired. However, these older accessories may require removal of the chassis cover for installation. 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 BLE versions. The exception is the JXP-*T, which is a taller version of the JXP jumpers. The JXP-*T will not fit in the older version BLE housing cover, so an older version JXP would need to be ordered for use with a tool for removal/installation, or a new and deeper housing should be ordered. BLE compatibility: If an electronics only package (Epack) is ordered, it will include the deeper housing cover to accommodate ergonomic accessories. Note: this is not the deeper housing cover associated with the status monitor. When ordering the status monitor option, a deep housing cover is also required. The reversible electronics package can be made backward compatible with the STARLINE JLX and 10-Amp BLE housing by installing the BLE- AMP 2 Kit. This kit contains 50 mil gold plated platform assemblies. This makes it possible for the amplifier to carry Amperes continuous through the input or output ports and up to 20 Amperes for 2 hours at +60 C. M-SPLIT DIPLEX FILTER OPTION Six different plug-in diplex filter options add to the flexibility of the, including the latest Mid-split, or M-split, diplex filter with a maximized return band of 5-80 MHz for advanced services including voice, video, and data. See details under Forward Path. 60/90 VOLT POWERING The is capable of 60 or 90 Vac powering. The power supply provides a regulated 24 Vdc output 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 (LO and HI) selector that sets the startup voltage of the power supply. 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) type surge suppressor for longer life over voltage protection. DIRECTIOL COUPLER TEST POINTS Other features include -20 db directional coupler test points at the forward input, forward output, return input and return output. The is enclosed in the BLE- HSG/ which allows access to test points without opening the housing. FORWARD PATH The operational gain of the 750 MHz silicon version is 29 db with db return loss. The 870 MHz silicon version achieves 30 db operational gain with return loss of db. All E-GaAs BLE amplifiers achieve 28 db of gain with 16 db return loss. Output level control is achieved through the use of an interstage Bode equalizer which compensates for coaxial cable

3 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. The 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), A splits (5-65 MHz/ MHz), and the newest M splits (5-80 MHz/ MHz) are also available. These same filters can be used for all Motorola RF distribution amplifiers. db or by 32 db with a controlled slew rate for minimum bit errors. The LIFELINE TM Broadband Line Extender transponder, model LL-BLE2, and accompanying deeper housing lid are required to operate the Ingress Control Switch from a remote location. NETWORK MONITORING The optional status monitoring transponder, model LL- BLE2, handles RF electronics performance, measurement control and alarm generation. The LL- BLE2 monitors AC line voltage, power supply voltage, RF level in forward and return, internal temperature and features an optical tamper switch. The LL-BLE2 is also used to control the optional ingress control switch. Various receive and transmit frequencies are available. Please refer to the configurator for options (see attached). RETURN PATH Return amplifier kits can be ordered with either high gain or low gain hybrids providing 24 db and 19 db minimum station gain, respectively. 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*T, which stabilizes gain and match over temperature extremes. When selecting the LL-BLE2 as an option, the deeper housing lid is required. CONFIGURATION To reduce customer costs and to accommodate customer specific needs, the STARLINE 2000 can be fully configured in the Motorola factory at no additional cost to the customer. Please refer to the attached configurator for options (see attached). Also available is Ingress Control Switching in 3 states.
