| GaAs SPDT Terminated Switch DC - 2.5 GHz Features * * * * * * * Very Low Power Consumption High Isolation: 30 dB up to 2 GHz Very High Intercept Point: 46 dBm IP3 Nanosecond Switching Speed Temperature Range: -40C to +85C Low Cost SOIC-8 Plastic Package Tape and Reel Packaging Available SW-338 V6 Functional Schematic Pin 1 V2 RFC V1 GND RF2 GND GND RF1 Description M/A-COM's SW-338 is a GaAs MMIC SPDT terminated switch in a low cost SOIC 8-lead surface mount plastic package. The SW-338 is ideally suited for use where very low power consumption is required. Typical applications include transmit/receive switching, switch matrices, and filter banks in systems such as radio and cellular equipment, PCM, GPS, fiber optic modules, and other battery powered radio equipment. The SW-338 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability.
