These graphs show mixer Third Order Intercept (TOI) vs. frequency referenced to the input of the mixer (that is, referenced
to the RF port in the case off a down-converter, or the IF port in the case of an up-converter), with both low-side LO excita-
tion (LO frequency below the RF frequency) and high side excitation (LO frequency above the RF frequency). Operation
both as a down-converter and an up-converter is shown, with LO powers of 10, 14, and 17dBm. In all cases, the IF fre-
quency is 100MHz. The RF power used in measuring third order intercept is +0dBm, except in cases where TOI exceeds
30dBm, in which case input power is increased to make the intermod tones visible above the noise floor.
