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.

is the temperature at the
bottom of the case.
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.
