Based on the data sheets for HMC1048LC3B (MIXER 2 - 18 GHz), can i used VCO input power with 8.52dBm. Currently i doing simulation in ADS software, can i still used the data as provided for vco 9dBm input in data sheet in simulation.
9.0 dBm is the lowest LO input power used during mixer characterization testing. I expect the performance degradation when using 8.5 instead of 9.0 dBm to be very small. But as the data sheet shows, the mixer does perform better with higher LO drive levels (13 to 17 dBm) . If you're trying to achieve the typical numbers you highlighted on the data sheet, it's probably best to use a gain block to boost the LO signal.
