Re: #qcxmini Can't adjust I-Q Balance, Phase Lo or Phase Hi #qcxmini


 

OK, that's reasonable. Now check pins 1,2,3,5,6&7 of ICs 5,6,7&8 looking for 2.5v. You should also see 2.5v on pins 5,6&7 of IC9, 4.9v on pins 1,2&3 of IC9 and half the input voltage on pins 1,2,3,5,6&7 of IC10.?

Hi Ron,

Thanks. I checked IC4 pins 7 and 9, I think. I attached a picture and show what I tested. Voltage at 7 is 2.52 and at 9 2.37
