Product Number: LT5579
Hello All,
I am using LT5579 for my project, however I have a problem that is much power drop.
Balun input is 21dBm, Balun output is 36dBm and LT5579 input is about 45dBm.
When C1 and C2 cap open, the power is normal condition.
Below is my hardware condition:
LT5579 Input Freq : 900MHz
LT5579 LO Freq : 1500MHz
LT5579 Output Freq : 2400MHz
I have a question. Is 900MHz possible with the IF Freq of LT5579?
If possible, how much should the capacitor capacity be used? (C1,C2,C3 and L1,L2,R1,R2 etc)
Of course, I read Figure 1 but there is no 900MHz input case.
I copied below schematic to my schematic.
And I use C1, C2 = 33pF, C3 = 33pF, L1, L2 = 40nH, R1,R2 = 11ohm.
