ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS
(Typical Application Circuit, VCC = +4.75V to +5.25V, no RF signals applied, all RF inputs and outputs terminated with 50
Ω,
267
Ω resistors connected from MAINBIAS and DIVBIAS to GND, TA = -40°C to +85°C, unless otherwise noted. Typical values are at
VCC = +5.0V, TA = +25°C, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
