The SW-392 is ideally suited for applications where very low power consumption (<20µA @ 3V), low intermodulation products, very small size and low cost required. Typical application is an Internal/External antenna select switch for portable telephones and data radios. In addition, because of its low loss, good isolation, and inherent speed, the SW-392 can be used in power applications up to 2 Watts in systems such as cellular, PCN, GSM and other analog/ digital wireless communications systems. The SW-392 is fabricated using a mature 1-micron gate length GaAs MESFET process. The process features full chip passivation for increased performance and reliability.
