3 Volt GaAs SPDT Switch, DC - 2.0 GHz SW-395 SW-395 3 Volt GaAs SPDT Switch DC - 2.0 GHz Features • • • • • SOT-26 Low Insertion Loss: <0.7 dB @ 900 MHz Low Power Consumption: <10µA @ =3 VDC Very High Intercept Point: 52 dBm IP3 Both Positive and Negative 3 to 8 V Control Low Cost SOT-26 Package 1 XX#Y PIN 1 Description M/A-COM’s SW-395 is a GaAs monolithic switch in a low cost SOT-26 surface mount plastic package. The SW-395 is ideally suited for applications where very low power consumption, low intermodulation products, very small size and low cost are 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-395 can be used as a conventional T/R switch or as an antenna diversity switch. The SW-395 can be used in power applications up to 0.5 Watts in systems such as cellular, PCN, GSM an other analog/digital wireless communications systems. 1. Dimensions are in: inches/mm Ordering Information Part Number Package SW-395 PIN SOT-26 Plastic Package SW-395TR Forward Tape and Reel 1 1. Refer to Application Note M513 for reel size information. The SW-395 is fabricated using a mature 1-micron gate length GaAs MESFET process. The process features full chip passivation for increased performance and reliability.
