Note 1: During power down status a load circuitry with dc-isolation to GND is assumed otherwise a current of
I
(V
S
–0.8 V) /RI has to be added to the above power down current for each output I, IX, Q, QX.
Note 2: The required LO-Level is a function of the LO-frequency (see figure 3).
Note 3: Measured with input matching. For 950 MHz the optional transmission line T3 at the RF input may be used
for this purpose. Noise figure measurements without using the differential output signal result in a worse noise
figure.
Note 4: Using Pins 7 and 8 as a symmetric RF input, the second order IIP can be improved.
