RFUV1702
Typical Electrical Performance
Measurements performed on connectorized evaluation board as shown on P.8 with I and Q (IF) ports connected to an external
90° Hybrid, LO Power = 0dBm and IF = 2.5GHz, -10dBm, V_LPA12 = 3.5V, I V_LPA12 = 120mA* , V_MPA = 4.5V, I V_MPA = 120mA**,
V_LOA1 = V_LOA2 = 4V and V_C1 = V_C2 = V_C3 = -4V, unless otherwise stated.
*Adjust V_G1 around -0.45V to get I V_LPA12 = 120mA
**Adjust V_G2 around -0.45V to get I V_MPA = 120mA
