In HMC8191 datasheet at the spurious performance section, we see many N/A (means not applicable). for example in the "up converter M x N spurious Outputs", the table for (IF = 2500 MHz, RF = 16000 MHz, LO = 18500 MHz, RF power = −10 dBm, LO power = 18 dBm, and TA = 25°C.) shows that 1LO-1IF is N/A. really what it means? it means we can not use this mixer for upconverting 2500MHz to 16000MHz by 18500MHz? but how this can be true? it means this mixer is not applicable for all frequencies???
Yes there are typos in the table. The 1IF-1LO should be Ref not N/A. I see a similar situation on a number of the other spurious information tables.
