SPURIOUS AND HARMONICS PERFORMANCE
LO harmonic isolation, LO = 15 dBm, all values are in dBc below
the input LO level at the RF port are positive, unless otherwise
noted.

RF = 9400 MHz at −10 dBm, LO = 9500 MHz at 15 dBm, data
taken without external hybrid, and all values are in dBc measured
below the IF power level (M × RF) − (N × LO) are positive,
unless otherwise noted.
