Section 2 Overview The Motorola BHA-100* is an 1003 MHz high gain indoor distribution amplifier with a silicon power-doubled output stage. It features variable gain and slope controls and is equipped with pad and equalizer facilities for greater flexibility when adjustment is required. It uses standard Motorola accessories, including JXP-*B pads, SFE-100-* forward equalizers, SRE-100-* return equalizers, and SCS-100-* cable simulators.
2-2 Overview Several models of the BHA-100* are available to accommodate various forward and return bandpass requirements, as described in Table 2-1: Table 2-1 BHA-100* models Model Number Forward Bandpass Return Bandpass Output Stage Forward Gain BHA-100S/P-R 52 to 1003 MHz 5 to 40 MHz Power-doubled 34 dB BHA-100K/P-R 54 to 1003 MHz 5 to 42 MHz Power-doubled 34 dB BHA-100A/P-R 85 to 1003 MHz 5 to 65 MHz Power-doubled 34 dB The recommended difference in signal level between the low an
Overview 2-3 Forward Amplifier Figure 2-2 illustrates a functional block diagram of both the forward amplifier and the optional return amplifier, and applies to all models.
2-4 Overview Accessories and Options You can upgrade all models to accommodate two-way service by installing an optional return amplifier kit, model BHA-100/RA-Kit/L. This kit enables the unit to carry channels in the extended bandwidth return path. Cable equalizers and plug-in pads are also available to enhance equipment performance.
Section 3 Configuration and Installation This section provides information to configure and install the BHA-100*, including instructions to: Mount the BHA-100* Configure the BHA-100* (add accessories) Connect and supply power to the BHA-100* Adjust the output level and slope Install the return amplifier kit Mounting the BHA-100* The BHA-100* should be mounted on a flat surface and be positioned vertically. This position results in maximum air flow and the lowest operating temperature.
3-2 Configuration and Installation Figure 3-1 illustrates the BHA-100* with outer cover removed and the power supply and amplifier board covers in place. The amplifier board cover shows the location of the options and the adjustments. Figure 3-1 BHA-100* with outer cover removed 101 Tournament Drive Horsham, PA 19044 POWER SUPPLY 90 - 240 VAC SERIAL NO.
Configuration and Installation 3-3 Connecting Power Power input to the amplifier can be 90 VAC to 240 VAC. Either 50 Hz or 60 Hz is acceptable and no internal adjustments are required. The furnished line cord is terminated in an IEC 320 connector. This connector mates with power cords manufactured to meet local standards. WARNING! This equipment operates over the marked voltage and frequency range without requiring the manual setting of any selector switches.
3-4 2 Configuration and Installation Remove the equalizer jumper and replace it with the appropriate value equalizer. The location of the cable equalizer is shown in Figure 3-2. If system drawings are unavailable, use the following procedures to determine and install the appropriate equalizer. This procedure assumes normal input signal is present and the amplifier is operational.

3-6 Configuration and Installation Figure 3-3 shows the equalizer slope versus equalizer value information presented in Table 3-1 as a graph. The amount of cable equals the equalizer value. Figure 3-3 Equalizer slope versus cable Refer to Figure 3-3 to determine the proper cable equalizer for the BHA-100*. For example, the input tilt derived from a channel near 550 MHz and a channel at the low end of the bandpass is 6 dB. According to the graph, the appropriate (closest) equalizer is model SFE-100-8.
Configuration and Installation 3-7 Starline Cable Simulators – SCS-* The Starline Cable Simulators, Model SCS-*, are used in place of fixed equalizers in systems where the amplifiers are located close together. The simulators are designed to fit in the same location as the equalizers. Table 3-2 helps you choose the correct simulators: Table 3-2 Starline Cable Simulators SCS-* 1 2 3 4 Frequency 5 6 7 8 9 10 Cable slope in dB 40 MHz 0.1 0.1 0.1 0.1 0.2 0.2 0.3 0.3 0.3 0.4 45 MHz 0.
3-8 4 Configuration and Installation Carefully install the return hybrid gain block in the location shown in Figure 3-2. The pins of the hybrid gain block are fragile and bend when forced. 5 Fasten the component with the hardware provided to complete the hybrid gain block installation. 6 Install the SRE-* return equalizer in the location shown in Figure 3-2. 7 Install JXP-*B zero attenuation pads in the appropriate locations.
