SPECIFICATIONS

All supply pins = 3.3 V, TA = 25°C, low-side LO injection, internal LO, minimum attenuation setting (DSA setting of 0 dB),

MIXER_GAIN_PEAK = 0, common-mode voltage (VCM) = 1.6 V, 25 Ω matching resistors on I/Q differential outputs, unless

otherwise noted. All losses from input and output traces and baluns are de-embedded from results.
