4 / 61 page  ADRF6821 Data Sheet Rev. A | Page 4 of 61 SYSTEM SPECIFICATIONS All supply pins = 3.3 V, TA = 25°C, internal LO, minimum attenuation setting (DSA setting of 0 dB), MIXER_GAIN_PEAK = 0, 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. Table 2.
