LO Leakage ADRV9009

I would like to get confirmation that the LO leakage looks to be higher than specification based on the following conditions:

1/ TX Attenuation = 25dB

2/Digital back-off 12 dB ( account for PAPR of NR OFDM)

3/ Output power = -16.79dBm

4/ Based on datasheet spec of -71dBFs, I was expecting the LO to be -16.79 -(-71 +25+12) dBm = -50.79 dBm

  • Whereas from plot below I see LO is around -40 dBm

5/ Can you suggest anything to improve the LO Leakage?
