Description
M/A-COM’s SW-219 is a GaAs MMIC SPDT switch
housed in a small, lead-free, 8-lead ceramic
package. The SW-219 is a low loss, high isolation
SPDT that has broadband application from DC to 3
GHz.
The CR-3 and CR-10 packages are
hermetically sealed, making these switches ideal for
space, military radios, or 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.
The SW-219 is fabricated as a monolithic GaAs
MMIC using a 1.0 micron MESFET process.
