MACOM's SW-485 is a GaAs PHEMT MMIC SPDT switch in a low cost SC-70 (SOT-363) surface mount plastic package. The SW-485 is ideally suited for applications where very small size and low cost are required. Typical applications are dual band systems where switching between small signal components are required such as filter banks, single-band LNAs, converters, etc. This part can be used for low power, low loss requirements in all systems operating up to 3 GHz, including PCS, GSM, DCS, Blue Tooth, and other Rx chain applications. The SW-485 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability.
