Theory Of Operation
A LINKNET AMPLIFIER MODULE is a Broad-Band Digitally Controlled Class-A
Amplifier. The most common LINKNET AMPLIFIER MODULE applications are the
extension of above ground signals into buildings, tunnels, vehicles or the extension
of radio coverage patterns into outdoor shaded areas such as deep valleys.
From an applications standpoint, an LINKNET AMPLIFIER MODULE is very similar
to a regular two-way radio repeater. On Frequency Radio Repeaters can be
combined using regular two-way radio multicoupling or duplexing equipment and
have input and output signal characteristics to those of regular transmitters and
receivers. The one special consideration in LINKNET AMPLIFIER MODULE
systems is that of input to output antenna isolation. This must be carefully
engineered for each installation.
These Modules are designed for indoor use only and are intended for mounting in a
standard EIA 19 inch rack. Modular design of LINKNET AMPLIFIER MODULE
circuitry allows for easy servicing, stocking of spares, adaptability and upgrade
ability.
