| RoHS Compliant GaAs SPST High Isolation Terminated Switch 0.3 - 4.0 GHz Features * * * * * * * * * High Isolation: 55 dB @ 2 GHz Insertion Loss: 1.6 dB @ 2 GHz Terminated RF Input in Isolation State Single Positive Control CMOS Compatible Logic Lead-Free 3 mm 12-Lead PQFN Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound RoHS* Compliant and 260C Reflow Compatible MASWSS0148 V1 Schematic with Off-Chip Components1 RFin CBlock 10 K VDD 1 VCTRL CBypass Description M/A-COM's MASWSS0148 is a GaAs monolithic single pole single throw (SPST) terminated switch in a lead-free 3 mm 12-lead PQFN plastic package. The MASWSS0148 is ideally suited for use where low power consumption, small size and high isolation are required. Typical applications include PCS and GSM LO switching, switch matrices and switched filter banks in systems such as radio and cellular equipment. The MASWSS0148 is fabricated using a mature 1-micron gate length GaAs MESFET process. The process features full chip passivation for increased performance and reliability. 1. 50 CBlock RFout VDD can be injected at either pin 5 or pin 11.
