Description
M/A-COM’s SW-449 is a GaAs MMIC SP3T switch in a low
cost MSOP-10 surface mount plastic package. The SW-449 is
ideally suited for applications where very low current consumption (<200µA), low intermodulation products, moderate power
handling and low cost are required. Typical applications include
switching for mobile handsets, radio cellular equipment, wireless LANs and other RF control circuits.
