Subject: Tuning Inductor value for EOM Driver 

 LTspice Results

  • Using the values for the bias tee found before, I investigated the possibility of tweaking a tuning inductor in the EOM Driver to retrieve the same resonance peak from before the bias tee introduction.
  • According to LTspice, a value of 926.5 nH is sufficient to reach a resonance peak at 37MHz.
  • This is within the range of the coil-craft tunable inductor 143-16J12L from https://www.coilcraft.com/uni10.cfm 
  • According to LTspice, a value of 978.7 nH is sufficient to reach a resonance peak at 36MHz, which is in range with the same inductor as above.
