Test Conditions and Bias Sequence
Measurements performed with I and Q (IF) ports connected to an external 90° Hybrid, LO Power = 0dBm and IF = 2.5GHz,
-10dBm, unless otherwise stated.
V_LOA1 = V_LOA2 = 4V, I_{LOA1, 2} = 205mA; V_LPA12 = 3.5V, Adjust V_G1 around -0.4V to get I_LPA12 = 120mA;
V_MPA = 4.5V, Adjust V_G2 to get I_MPA = 120mA; I_TOTAL = 445mA, V_C1 = V_C2 = -4V
