MASW-007935 GaAs SPDT Terminated Switch Rev. V2 DC - 3.0 GHz Features Functional Schematic Low Insertion Loss: 0.5 dB typical up to 1 GHz Positive Control Voltage High Isolation: > 38 dB 900 MHz Low Power Consumption: < 10A -3 V C = 39 pF C = 100 pF C = 100 pF Positive or Negative 2.5 to 8 V Control Lead-Free SOT-26 Package V1 RFC V2 100% Matte Tin Plating over Copper Halogen-Free Green Mold Compound 260C Reflow Compatible RoHS* Compliant Version of SW-442 Description M/A-COMs MASW-007935 is a GaAs monolithic RF1 GND RF2 switch in a low cost lead-free SOT-26 surface mount Pin 1 plastic package. The MASW-007935 is ideally suited C = 39 pF CGND C = 39 pF for applications where very low power consumption, low insertion loss and very small size are required. Typical application is in dual band systems which Functional Schematic require switching between small signal components Negative Control Voltage such as filter banks, single band LNA s, converters etc. The MASW-007935 can be used in applications up to 0.25 Watts in systems such as CDMA, W- V1 RFC V2 CDMA, PCS, DCS1800, GSM and other analog/ digital wireless communications systems. The MASW-007935 is fabricated using a mature 0.5 micron GaAs PHEMT process. The process features full passivation for increased performance and reliability.
