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?
