SPURIOUS AND HARMONICS PERFORMANCE
Mixer spurious products are measured in dBc from the IF output
power level. N/A means not applicable.
LO Harmonics
LO = 13 dBm, all values in dBc are below input LO level and are
measured at the RF port.

M × N Spurious Outputs
Downconverter, Upper Sideband
Spur values are (M × RF) − (N × LO). RF = 28 GHz at
−10 dBm, LO = 27 GHz at 13 dBm.
