    I need a simple square wave amplifier for a project. It needs to amplify a
    Square wave 6 to 12 X in the 72 MHZ Band. Can anyone email me a schematic
    or refference the same?
    thanks
     
  2. There is no such thing as a perfect square wave, in practice. How
    much output voltage swing and what rise and fall time do you require?
    And what load impedance must this amplifier drive?

    You can't have a square wave in a band. You need a response to DC to
    preserve the flat tops, and a response to infinity to preserve the
    vertical sides. So you need to specify what you will tolerate in rise
    time and droop to arrive at an amplifier.

    What will be the impedance of the load?

    Do you actually need a linear amplifier, or could you settle for an output
    that is at a larger fixed amplitude?
