Description

The SW-439 is a GaAs MMIC SPDT switch in a low

cost

MSOP-10

surface

mount

plastic

package. This part is ideal for high isolation,

broadband

switching

requirements.

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-439 is fabricated as a monolithic GaAs

MMIC using a 0.5 micron pHEMT process.

The

process features full passivation.
