| RoHS Compliant GaAs SPDT Switch DC - 2.5 GHz Features * * * * * * * * * * Very Low DC Power Consumption: 100 W Low Insertion Loss: 0.5 dB High Isolation: 25 dB up to 2 GHz Very High Intercept Point: 45 dBm IP3 Nanosecond Switching Speed Lead-Free SOIC-8 Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound 260C Reflow Compatible RoHS* Compliant Version of the SW-239 MASWSS0157 V3 Functional Schematic Pin 8 GND GND RF2 B Description M/A-COM's MASWSS0157 is a GaAs MMIC SPDT switch in a lead-free SOIC 8-lead surface mount plastic package. The MASWSS0157 is ideally suited for use where low power consumption is required. Typical applications include transmit/receive switching, switch matrices and switched filter banks in systems such as radio and cellular equipment, PCM, GPS, fiber optic modules, and other battery powered radio equipment. The MASWSS0157 is fabricated using a monolithic GaAs MMIC using a mature 1 micron process. The process features full chip passivation for increased performance and reliability.
