V 2.00

High Power GaAs SPDT Switch

SW-106, SW-276

Absolute Maximum Ratings

1. Operation of this device above any one of these parameters ma y cause

permanent damage.

2. Tcase = 25˚C, where Tcase is the temperature at the bottom

of the case.

3. Special consideration must be given to the mounting of the switch to

minimize the thermal resistance. The bottom of the case should be

thermally attached to the mounting surface to maintain the junction

temperature under the absolute maximum rating.
