The following pictures show typical results of measurements that made over a 50 KHz to 3.5MHz frequency range.
Figure 6. 75W Return Loss Measurement
Figure 6 shows a return loss better than 20dB at low frequencies that decreases to about 12dB at 3.5MHz. Since the
source and load resistances are well--matched, the return loss degradation is due to the transformer.
Figure 7. 120W Return Loss Measurement
Figure 7 shows that for the 120W case, transformer characteristics improve return loss at lower frequencies. At 3.5 MHz,
return loss is close to the calculated 13.8dB for a 75W source terminated with 120W.
