Description

M/A-COM’s SW-276 is a broadband GaAs SPDT

switch available in a lead-free, 7-lead ceramic

package.

The package is hermetically sealed,

making this switch ideal for space, military radios

and other environmentally harsh applications.

Typical applications include synthesizer switching,

transmit / receive switching, switch matrices and

filter banks in systems such as radio and cellular

equipment, PCM, GPS and fiber optic modules.

M/A-COM fabricates the SW-276 using a 1.0-micron

gate length MESFET process. The process features

full chip passivation for performance and reliability.

6. 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.
