Could you provide the IM3 spec of ADL5604?
Customer need to understand this parameter for design.
The answers are in the data sheet, but captured in form of OIP3 (Output Third-Order Intercept).
Here is the mathematical relationship between OIP3 and IMD3:
OIP3 = Pout + IMD3 / 2
Using ADL5604 typical spec at 2140MHz as example (table 1, page 3, data sheet):
OIP3 = 42.1 dBm = Pout + IMD3 / 2 = 14 dBm + IMD3 / 2
Now, you should be able to calculate the IMD3 = 56.2 dB, under this particular test condition.
Thanks for your support!
This is helpful to me.
