SW-395 3 V GaAs SPDT Switch DC - 2.0 GHz Rev. V7 Functional Schematic 5 Features • • • • • Low Insertion Loss: <0.5 dB @ 900 MHz Low Power Consumption: <10 µA @ 3 VDC Very High Intercept Point: 52 dBm IP3 Both Positive and Negative 3 to 8 V Control Low Cost SOT-26 Package 6 5 4 1 2 3 Description M/A-COM’s SW-395 is a GaAs single pole, double throw 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, PCS, GSM and other analog / digital wireless communications systems. The SW-395 is fabricated using a mature 0.5-micron gate length GaAs PHEMT process. The process features full chip passivation for increased performance and reliability. Ordering Information 5.
