| RoHS Compliant 3 Watt Cellular T/R and Antenna Changeover Switch DC - 3.0 GHz Features * * * * * * * * * * Low Insertion Loss: < 0.4 dB @ 1900 MHz Low Current Consumption: <20 A @ +5V High Intercept Point: 58 dBm @ 1 GHz Positive or Negative Voltage Control CDMA, W-CDMA, TDMA, GSM, PCS and DCS Lead-Free Plastic SOT-26 Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of SW-425 MASWSS0143 V4 Functional Block Diagram 39 pF VA RFC VB Description M/A-COM's MASWSS0143 is a GaAs monolithic switch in a lead-free, SOT-26 surface mount plastic package. The MASWSS0143 is ideally suited for applications where very low power consumption, 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 MASWSS0143 can be used as a conventional T/R switch or as an antenna diversity switch. The MASWSS0143 can be used in power applications up to 3 watts in systems such as cellular PCS, CDMA, W-CDMA, TDMA, GSM and other analog / digital wireless communications systems. The MASWSS0143 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full chip passivation for increased performance and reliability.
