2.1 INTRODUCTION 

 
The 2100L RF amplifier is used to amplify the RF level of signal sources in the 10 
KHz to 12 MHz range. No tuning or any other form of adjustment is required.  
 
The 2100L will work into any load impedance. Into a short circuit or infinite load 
at  some  phase  angles  it  may  protect  itself  at  power  greater  than  80%  rated 
power  output.  Any  power  reflected  due  to  output  load  mismatch  is  absorbed  in 
the  amplifier.  Therefore,  although  the  output  impedance  is  50  ohms  (maximum 
VSWR: 2:1), the amplifier will work into any load impedance.
