Motorola BDA-S4 , a Broadband Drop Amplifier

Motorola BDA-S4 is the amplifier for cable TV, both analog and HDTV which has four ports.

This amplifier is well made, durable and meets all of the requirements for professional use. It's is widely used in the cable industry (contrary to some of the reviews here). There are several companies that make these and they all meet the frequency requirements (5-1000 MHz) for modern HFC cable systems. It is provided and installed by cable guys and it costs $40-$50 on average

There is nothing worse than having a great TV to watch your favorite programs, while having a grainy or pixilated (digital cable) picture. Motorola BDA amplifiers give your TV signal a boost while maintaining full compatibility with all of your cable services. Simply install the BDA-S4 where your cable or antenna comes into your house and begin enjoying a better picture, faster downloads, and a more reliable HD or Digital TV signal. With a name like Motorola, how can you go wrong? The BDA-S4 is fully compatible with all cable TV standards, cable boxes, cable modems, routers, HDTV and more

GALLIUM ARSENIDE TECHNOLOGY
The BDA amplifier uses advanced Gallium Arsenide technology for improved distortion and noise performance. This technology provides improved distortion performance for both CTB and CSO distortions. Compared to silicon-based amplifiers, GaAs distortion performance remains linear at significantly higher output levels

TWO-WAY CAPABLE
The BDA amplifier has built-in diplex filters for two-way operation. A passive return path is provided for return path continuity and enables use of multiple broadband devices such as set-top terminals and cable modems. An active return path is provided for the BDA-K*/PS/RA to overcome external splitting losses. The BDA is available with extended return S-split (42/52 MHz) diplex filters for the passive return models, and traditional K-split diplex filters (42/54 MHz) for the active return models. Please note the S-split return frequency for the BDA passive return models differs slightly from the traditional S-split offered in other Motorola products that use a 5-40 MHz return path. Please contact your Motorola Account Representative for specific details.

SURGE TOLERANT
The BDA amplifier is designed to meet the 6 kV IEEE C62.41-1991 Category B-3 Combination Wave at the input port. It is also designed to meet both 6 kV IEEE C62.41-1991 Category A-3 Ring Wave and 1 kV Combination Wave surge for all output ports, power supply transformer port, and power inserter ports. This surge tolerance enhances system reliability.

INDOOR OR OUTDOOR APPLICATIONS
A weather seal and protective coating are provided so that the BDA amplifier may be used for indoor or outdoor applications
