1. All specifications apply when operated with bias voltages of 0V for Vin Low
and -5 to -10V for Vin High, and 50 ohm impedance at all RFports, unless
otherwise specified.

2. High power (greater than 1W) handling specifications apply to cold switching
only.For input powers under 1W hot switching can be used.

3. Contact the factory for standard or custom screening requirements.

Absolute Maximum Ratings

1. Operation of this device above any one of these parameters may cause
permanent damage.

2. T

case

= 25˚C, where T

case

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.
