Description 
The Compact Mini Amplifier type 93191 is a small, cost-effective 
amplifier in 28 and 36 dB gain versions that address the divergent 
needs of today’s broadband networks. In addition, GaAs-FET 
technology is utilized for longer system reach and superior 
distortion performance. A compact design and reduced power 
consumption enable this mini amplifier to make significant 
contributions to efficient end-of-line applications. 
  
The Compact Mini Amplifiers share common plug-in accessories 
with the Compact Amplifier Platform to lower your cost of spares. 
The same plug-in pad is used for both attenuation and 
equalization, which minimizes the overall number of plug-ins. 
 
Both attenuators and equalizers are plug-in pads with fixed values 
to provide maximum user friendliness. In case it is necessary to 
replace the amplifier in the network, this is easily done as the pads are simply moved to the new amplifier.  
 
The amplifier provides a single, high-level forward RF output that can be split to provide two outputs by using 
an optional splitter/directional coupler plug-in. 
 
The Compact Mini Amplifier 93191 utilizes a reverse amplifier module with push-pull technology, and is 
equipped with a reverse input attenuator to maximize the cable modem transmitter output levels. The plug-in 
reverse amplifier module and diplex filters provide a free choice of frequency range. 
 
The Compact Mini Amplifier 93191 is equipped with directional coupler RF test points at the forward output 
allowing for accurate signal level measurement, and reverse signal injection during setup and alignment. 
Surge protection is provided for all input and output ports and the mini amplifier are equipped with a double 
gasket; that includes an RF and a water-dust gasket.
