Other Parts Discussed in Thread: DAC38J84, TRF370417
My customer is using the TRF370417EVM with the following modifications (see attached)
LO : 2 to 6 GHz
I/Q: 50 to 500 MHz
While the conversion loss seems right and matches the datasheet, the LO and image rejection they receive in the high frequencies is only 20-25dB.
As these numbers are getting worse as the frequency increase and as they're far from what is described on the datasheet I wanted to have your advise on what might be wrong in the setup.
