(1) _{Given for FBB = 10MHz and VBBI = VBBQ = 200mVpp (over 50Ω) and PLO = 0dBm}
(2) _{LO leakage without cancelation (i.e. no DC tuning: VI_DC = VQ_DC = 0V)}
(3) _{LO leakage cancelation (i.e. with DC tuning on VI_DC and VQ_DC)}
(4) _{Use to cancel LO leakage. Differential mode means I and Ib voltage are opposite. Tuning}
adjustment are need for each frequency, temperature and LO power.
(5) _{Peak to Peak Voltage.}
These values are representative of onboard measurements as defined on the drawing in
paragraph "Evaluation mother board".
