I'm using the ADL5380 demodulator for a RF design operating in the range between 4.4GHz -5GHz. I alredy read the discussion "adl5380 matching circuits for RF/LO ports" but the frequency range was larger so I have two questions:
1.Examining the graph in Figure 78 in datasheet is appropriate to use a balun 50/100 ohms and not 50/50 as those recommended in the datasheet ?
2.Is there a way to get a good RF/LO impedance match with a 50:100 Ohm balun for the ADL5380 in this range (4.4GHz to 5GHz) ?
Due to progect restrictions I cannot use the single-ended configuration proposed in fig.84. Any circuit recommendations or solution would be greatly appreciated.
Best regards and thanks.
