SW-437 GaAs SPDT Switch DC - 3.0 GHz Rev. V5 Features • • • • Low Cost Plastic SOT-363 Package Low Insertion Loss <0.3 dB @900 MHz Low Power Consumption <15µA @ +2.7V Positive or Negative 2.5 to 8 V Control Functional Schematic Positive Control Voltage Description M/A-COM’s SW-437 is a GaAs monolithic switch in a low cost SOT-363 surface mount plastic package. The SW-437 is ideally suited for applications where very low power consumption, low insertion loss, very small size and low cost are required. Typical application is in dual band systems where switching between small signal components is required such as filter banks, single band LNA’s, converters etc. The SW-437 can be used in applications up to 0.25 Watts in systems such as cellular, PCS, DCS1800, GSM, CDMA, W-CDMA and other analog/digital wireless communications systems. Functional Schematic Negative Control Voltage The SW-437 is fabricated using a mature 0.5 micron GaAs PHEMT process. The process features full passivation for increased performance and reliability.

If negative control is used, DC blocking capacitors are not required on RF ports. This switch is not meant to pass or switch a DC voltage. Handling Procedures Please observe the following precautions to avoid damage: Static Sensitivity Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. 2 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 is considering for development.
