4 Watt SP3T GaAs Switch
500 - 2000 MHz
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 consump-
tion (<200μA), low intermodulation products, moderate power
handling and low cost are required. Typical applications include
switching for mobile handsets, radio cellular equipment, wire-
less LANs and other RF control circuits.
The SW-449 is fabricated using a 0.5 micron gate length GaAs
pHEMT process. The process features full passivation for
increased performance and reliability.
