Dear,
My customer is testing EVK ADRV9009, having issues as below.
1. ADRV9009, CW at 61.44, carier freq 3.5GHz. Customer see LO leakage so high at 3.5 Ghz. Customer wants to know how to reduce LO leakage?
2. Customer did test with project ref design of ADI, using iio scope
Capture CW signal one tone 61.44MHz, LO 3438.56 MHz, loopback from TX of EVK ADRV9009, signal not stable.
Any advise for customer? Below is images and log file.
