| GaAs SPDT Switch 0.05 - 3 GHz Features * * * * Low Insertion Loss: 0.35 dB @ 2.4 GHz Moderate Isolation: 21 dB @ 2.4 GHz Low Current Consumption: 5 A @ 2.5 V Low Cost Plastic SOT-26 Package MASWSS0005 V4 Functional Schematic C=39pF V1 RFC V2 Description M/A-COM's MASWSS0005 is a GaAs PHEMT MMIC single pole, double throw (SPDT) switch in a low cost SOT-26 surface mount plastic package. The MASWSS0005 is ideally suited for applications where small size and low cost are required. Typical applications are dual band systems which require switching between small signal components such as filter banks, single-band LNAs, converters, etc. This part can be used for low power, low loss requirements in all systems operating up to 3 GHz, including PCS, GSM, DCS, Satellite Radio, Blue Tooth, and other receive chain applications. The MASWSS0005 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability.

For positive voltage control, external DC blocking capacitors are required on all RF ports. 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.
