SW-442 GaAs SPDT Terminated Switch DC - 3.0 GHz Features • • • • • • Low Insertion Loss: 0.5 dB typical up to 1 GHz High Isolation: > 38 dB @ 900 MHz Low Power Consumption: < 10µA @ -3 V Positive or Negative 2.5 to 8 V Control Low cost SOT-26 Package Available in a lead free version: MASW-007935 Rev. V4 Functional Schematic Positive Control Voltage Description M/A-COM’s SW-442 is a GaAs monolithic switch in a low cost SOT-26 surface mount plastic package. The SW-442 is ideally suited for applications where very low power consumption, low insertion loss and very small size are required. Typical application is in dual band systems which require switching between small signal components such as filter banks, single band LNA's, converters etc. The SW-442 can be used in applications up to 0.25 Watts in systems such as CDMA, W-CDMA, PCS, DCS1800, GSM and other analog/digital wireless communications systems. Functional Schematic Negative Control Voltage The SW-442 is fabricated using a mature 0.5 micron GaAs PHEMT process. The process features full passivation for increased performance and reliability.

External DC blocking capacitors are required on all RF ports when using positive voltage control. 4. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 1 GHz, 39 pF for 0.5 GHz - 3 GHz.
