3 Watt Cellular T/R and Antenna Changeover Switch, DC - 3.0 GHz .. SW-425 SW-425 3 Watt Cellular T/R and Antenna Changeover Switch, DC - 3.0 GHz Features - Low Cost Plastic SOT-26 Package - Low Insertion Loss <0.6d B @ 1900 MHz - Low Power Consumption <20µA @ +3V - Very High Intercept Point: 53 d Bm IP3 - Both Positive and Negative 2.5 to 8 V Control - For CDMA, W-CDMA, TDMA, GSM, PCS and DCS .. Applications SOT-26 Plastic Package XX#Y PIN 1 Description M/A-’s SW-425 is a Ga As monolithic switch in a low cost SOT-26 surface mount plastic package. The SW-425 is ideally suited for applications where very low power consumption (<10µA@5V), low intermodulation products and very small size are required. Typical applications include 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-425 can be used as a conventional T/R switch or as an antenna diversity switch. The SW-425 can be used in power applications up to 3 watts in systems such as celluar PCS, CDMA, W-CDMA, TDMA, GSM and other analog/digital wireless munications systems. The SW-425 is fabricated using a new 0.5 micron gate length Ga As PHEMT process. The process Features full chip passivation for increased performance and reliability.
