MASWSS0143 3 Watt Cellular T/R and Antenna Changeover Switch Rev. V5 DC - 3.0 GHz Features Functional Block Diagram Low Insertion Loss: < 0.4 dB 1900 MHz Low Current Consumption: <20 A +5V 39 pF High Intercept Point: 58 dBm 1 GHz Positive or Negative Voltage Control CDMA, W-CDMA, TDMA, GSM, PCS and DCS VA VB RFC Lead-Free Plastic SOT-26 Package Halogen-Free Green Mold Compound 260C Reflow Compatible RoHS* Compliant Version of SW-425 Description The MASWSS0143 is a GaAs monolithic switch in a lead-free, SOT-26 surface mount plastic package. RF1 GND RF2 This device is ideally suited for applications Pin 1 where very low power consumption, low intermodulation products and very small size are 39 pF 39 pF required. Typical applications include internal / external antenna select switch for portable telephones and Pin Configuration data radios. In addition because of its low loss, good isolation, and inherent speed, the MASWSS0143 Pin No. Function Description can be used as a conventional T/R switch or as an 1 RF1 RF In/Out antenna diversity switch. 2 GND RF Ground The MASWSS0143 can be used in power 3 RF2 RF In/Out applications up to 3 watts in systems such as cellular 4 VB Voltage Control B PCS, CDMA, W-CDMA, TDMA, GSM and other analog / digital wireless communications systems. 5 RFC RF Common 6 VA Voltage Control A The MASWSS0143 is fabricated using a 0.5 micron gate length GaAs pHEMT process. The process features full chip passivation for increased 2,3 Absolute Maximum Ratings performance and reliability.
