Chapter   1 Introduction 

 

 
The  A  1000  is  a  broadband  solid  state  amplifier  covering  the  frequency  spectrum  from 
300  KHz  to  35  MHz.  It  is  rated  at  1000  watts  of  RF  power  with  low  harmonic  and 
intermodulation  distortion.  Over  1500  watts  of  saturated  power  can  be  produced  with 
increased  distortion  products.  A  linear  Class  A  design,  the  A1000  will  amplify  inputs  of 
AM, FM, SSB, pulse and any complex modulation signals. The amplifier has 60 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 208 V three phase AC power/ max 30 Amps.  
 
 

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
