3. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

1. Required LO level is a function of the LO frequency.
2. The LO input impedance is consisting of a 50
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.
