Description

M/A-COM’s SW-338 is a GaAs MMIC SPDT

terminated switch in a low cost SOIC 8-lead surface

mount plastic package. The SW-338 is ideally suited

for use where very low power consumption is

required.

Typical applications include transmit/receive switch-

ing, switch matrices, and filter banks in systems

such as radio and cellular equipment, PCM, GPS,

fiber optic modules, and other battery powered radio

equipment.

The SW-338 is fabricated with a monolithic GaAs

MMIC using a mature 1-micron process. The

process features full chip passivation for increased

performance and reliability.
