This SLIM is constructed on a common printed wiring board, the PWB-MOB.  Click to go to the page describing the Master Osc or Buffer.

    The purpose of the SLIM-BSQ is to take a signal, buffer it, square the waveform, and drive up to 3 separate users.  The input signal can be a sine or square wave with a level from -10 dBm to +18 dBm.  The input impedance is determined by the value of R9.
    The Buffer Squarer contains a center biased buffer and 3 line drivers.  Each output is 5 volt CMOS that can drive a 50 ohm line that is terminated with either, a high impedance load, or 50 ohms.  A 50 ohm resistor is shown as a series element in each output.
    For a 50 ohm line, with a high impedance load at the end of that line, the mismatched load will create a reflection.  The reflected signal will be dissipated in the series 50 ohm resistor.
    For a 50 ohm line, with a 50 ohm load at the end of that line, the 50 ohm load will receive a 2.5 volt peak to peak square wave.  If this is not sufficient, the 50 ohm series resistor can be replaced with a low impedance coupling capacitor (.01 uf for 64 MHz).
