This is the spur table for the Analog Devices ADL5801. Note that the 1x1 term, the IF fundamental, is given as 0 dB. The values in mixer tables are often normalized to the amplitude of the IF output. RF power is given so that if the conversion gain is known, the absolute IF output power can be calculated. LO power is given because harmonic content can be affected by how hard the LO port is driven. Bear in mind that this table is valid for only one RF/LO combination. In this case Frf = 900 MHz and Flo = 703 MHz, the resulting RF/LO ratio is ~ 9/7 (low side injection).
