Notes:

1. Required LO level is a function of the LO frequency.

2. The LO input impedance is consisting of a 50

Ω resistor in series with a 15 pF capacitor.

3. With the pins 19 and 20 spurious performance especially for low frequency application can be improved by adding a chip

capacitor between LP1 and LP2. In conjunction with a parallel resistor the output level can be adjusted to the following

mixer stage without degration of LO suppression and noise performance which would decrease if the I/Q input level is

reduced
