Chapter   1 Introduction 

 

 
The 2200L is a broadband solid state amplifier covering the frequency spectrum from 10 
KHz  to  12  MHz.  It  is  rated  at  200  watts  of  RF  power  with  low  harmonic  and 
intermodulation  distortion.  Over  300  watts  of  saturated  power  can  be  produced  with 
increased distortion products. A highly linear Class A design, the 2200L will amplify inputs 
of  AM,  FM,  SSB,  pulse  and  any  complex  modulation  signals.  The  amplifier  has  53  dB 
gain,  it  is  unconditionally  stable  and  will  not  oscillate  even  with  combinations  of 
mismatched source and load impedance. It is protected against failure due to output load 
mismatch and/or overdrive. 
 
RMS forward and reverse powers are monitored by a front panel meter. An integral power 
supply permits operation from 115/230 single phase AC power. 
 

1.2     INSTRUMENTATION IDENTIFICATION 

 
Each amplifier is identified by a serial number tag on the back panel of the unit. Both the 
model number and the serial number should be quoted to identify specific unit.  
 

1.3      SPECIFICATIONS 

 
Physical and electrical specifications are listed in Table 1-1 below
