The following pictures show typical results of measurements that made over a 50 KHz to 3.5MHz frequency range.
Figure 6. 75
Return Loss Measurement
Figure 6,
shows a returnloss betterthan20dB atlowfrequencies thatdecreases to about12dB at3.5MHz. Since the
source and load resistances are well--matched, the return loss degradation is due to the transformer.
Figure 7. 120
Return Loss Measurement
Figure 7,
shows that for the 120
case, transformer characteristics improve return loss at lower frequencies. At 3.5
MHz, return loss is close to the calculated 13.8dB for a 75
source terminated with 120
