Description
M/A-COM’s SW-243 GaAs MMIC SP4T switch is
packaged in a CR-4 surface mount ceramic style
package. The SW-243 is a reflective switch,
optimized for low insertion loss. The CR-4 package
is hermetically sealed, making these switches ideal
for space, military radios, or other environmentally
harsh applications.
Typical applications include synthesizer switching,
switch matrices and filter banks in systems such as
military radios, and space equipment.
The SW-243 is fabricated as a monolithic GaAs
MMIC using a 1.0 micron MESFET process.
