A 50-ohm source has an RMS open-circuit output voltage of 1 volt at 100 MHz a. What peak voltage will appear across a 50-ohm load connected to this source b. Express this voltage in dBm. (Hint: careful of peak/rms voltage.) c. If the source is connected to the 50-ohm load through a lossless 50-ohm cable, what will the peak voltage at the load be? d. e. If the source is connected through a 50-ohm load through a 100-ft lossy 50-ohm cable, and the loss is 0.5 dB/10 ft, what will be the peak voltage at the load? Say that the "peak" (not RMS) voltage in part a. was 1 volt (i.e. the sinusoidal signal ranged from -1 to +1 volts). What would be the reading across a 50-ohm load in this case, if measured by a spectrum analyzer? Note that a spectrum analyzer produces a reading in dBm, not volts. Assume are no cables in this case.
