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.
