The WMA-300 HV amplifier: 
general description 

 

The  Falco  Systems  WMA-300  is  a  high 
speed,  high-voltage  linear  laboratory 
amplifier  for  demanding  applications.  Its 
wide bandwidth and large voltage range  

 
make  it  an  excellent  choice  for  use  with 
MEMS  devices,  EO-modulators,  piezo 
positioning  systems,  beam  steering, 
ultrasonics,  dielectric  studies,  and  many 
others. 
Through  the  extensive  use  of  computer 
modelling  and  state-of-the-art  design 
concepts,  this  amplifier  can  be  used  in 
many  applications,  including  those  where 
conventional  amplifiers  are  difficult  to 
apply. It is designed to be absolutely stable 
and  free  of  spurious  signals  with  any 
capacitive load.  
The  amplification  is  50x  (fixed).  With  a 
range  of  –150V  to  +150V,  a  large  signal 
bandwidth  of  5MHz  @  -3dB  and  a  typical 
slew  rate  of  2000V/μs,  this  amplifier  will
