| RoHS Compliant 3 V GaAs SPDT Switch DC - 2.0 GHz Features * * * * * * * * * Low Insertion Loss: <0.5 dB @ 900 MHz Low Power Consumption: <10 A @ 3 VDC Very High Intercept Point: 52 dBm IP3 Both Positive and Negative 3 to 8 V Control Lead-Free SOT-26 Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of SW-395 MASWSS0179 V2 Functional Schematic 2 6 5 4 Description M/A-COM's MASWSS0179 is a GaAs single pole, double throw switch in a lead-free SOT-26 surface mount plastic package. The MASWSS0179 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 MASWSS0179 can be used as a conventional T/R switch or as an antenna diversity switch. The MASWSS0179 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 MASWSS0179 is fabricated using a mature 0.5micron gate length GaAs PHEMT process. The process features full chip passivation for increased performance and reliability. 1 2 3 2.
