| RoHS Compliant GaAs SP3T 2.6 V CDMA-GPS Switch 0.5 - 3.0 GHz Features * * * * * * * * * Optimized RF Paths Low Cross Modulation Low Insertion Loss: 0.7 dB at 820 MHz (Cell) High Isolation: 21.5 dB at 1.9 GHz (PCS) 0.5 micron GaAs PHEMT Process Lead-Free 2 mm 8-lead STDFN Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound RoHS* Compliant and 260C Reflow Compatible MASWSS0191 V1 Functional Block Diagram Description M/A-COM's MASWSS0191 is an industry leading GaAs PHEMT MMIC single pole three throw (SP3T) CDMA-GPS switch in a 2 mm 8-lead STDFN package. The MASWSS0191 is uniquely configured to enable switching from a common antenna port to CDMA cellular, CDMA PCS, or GPS ports. The design is asymmetric and has been fully optimized for excellent cross modulation performance in CELL and PCS paths while still maintaining excellent insertion loss and isolation. The MASWSS0191 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability. Pin Configuration Pin No. 1 2 3 4 5 6 7 8 9 2.
