In-Hancer Plus BDA
USER MANUAL
Overview
Introduction
The In-Hancer Plus family is a modular Bi-Directional Amplifier product. BiDirectional Amplifiers (BDA’s) are radio frequency amplifiers that amplify signals in
two directions. There are two basic BDA Applications; "Line Amplifiers" and “Off-Air”. Line Amplifiers are low gain (40 dB typical), while Off-Air are high gain (80 dB
typical). The In-Hancer Plus does NOT have separate models for these two
applications, but rather uses non volatile memory and software settings for gain.
Line Amplifier BDA's
An In-building RF distribution system takes on one of several forms including, but
limited to, radiating cable, distributed tapped radiators, or high power repeater
antennas. For an in-building RF distribution system that requires some gain to
compensate for the system loss, Line Amplifier BDA's are best for the job. Line
Amplifiers provide amplification of RF signals to recover signal loss contributed by
radiating cable and other system components. The Figure below shows an example
of a Tunnel RF Distribution System using Line Amplifiers. The system consists of
Line Amplifiers strategically inserted between radiating cables. As the RF signal
travels along the radiating cable, it loses signal strength. Line Amplifiers compensate
for the RF loss by amplifying the signal back to the desired signal strength before
sending it down the next distribution section, thus maintaining in-building RF
seamless coverage.

USER MANUAL
Off-Air Operation BDA's
Off-Air BDA's are intended to extend coverage into areas with coverage deficiency
such as inside office buildings, shopping malls, hospitals, etc. They are designed to
be located independently of the donor site and must be equipped with their own
antenna systems - one to communicate with the donor site and the other(s) to
communicate with portables in the shadow zone. A typical in-building coverage
extension system is shown below. The "Head-End" BDA is responsible for the
amplification of both incoming “Off-Air” downlink signals and outgoing uplink signals.
The in-building distribution antenna system comprises of Coaxial cable, Signal taps,
splitters and antennas to extend coverage on every floor, basement and
underground parking garage.

This distributed antenna system is based on Kaval Wireless Technologies’ “Tapped
Radiator” RF signal distribution approach. The technology makes use of coaxial
cable with Signal Taps strategically located and connected to Omni-directional
ground plane antennas. This technology offers flexibility in system design,
installation and optimization. Once the RF cable backbone has been installed,
additional signal taps and antennas can quickly and easily be added to a live
system, without the need to take the system out of service. Hence, new coverage
areas can be added, or the system can easily be modified if the layout should
change (e.g. modernization retrofits or process modifications).

In-Hancer Plus BDA
USER MANUAL
Modular Construction
The basic In-Hancer Plus BDA building blocks are.
• RF-Deck: an Amplifier and Controller assembly mounted on a heat-sink
ready to install in an enclosure or rack. These include RF output Isolators.
• Enclosure including Power Supply.
• Optional Batteries for backup.
• Filter Kit including Duplexers, Filters and mounting hardware, if not already
included in base Model.
This manual lists complete Standard Models, some of which are complete products
as is, and others require the selection of a Filter Kit. There is also a series of addon Accessories and Options.
Theory Of Operation
The In-Hancer Plus BDA uses the RF-Deck as the fundamental active element. RFDecks include both Uplink and Downlink RF Amplifiers, Microprocessor based
Controller, and Power Supply / Battery Charging...
