    The PWB-MOB is a printed wiring board, that is layed out to allow construction of either an oscillator or buffer.  It will take that signal, 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 PWB-MOB 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 resistor is shown as a series element in each output, but can be changed to capacitors.
