| SW-485 GaAs SPDT Switch 0.05 - 3.0 GHz Features * * * * Low Insertion Loss: 0.3 dB Typ. @ 2.4 GHz Isolation: 21 dB @ 2.4 GHz Low Power Consumption: <5 A @ +2.3V Low Cost Plastic SOT-363 Package Rev. V4 Functional Schematic C=39pF V1 RFC V2 Description M/A-COM's SW-485 is a GaAs PHEMT MMIC SPDT switch in a low cost SC-70 (SOT-363) surface mount plastic package. The SW-485 is ideally suited for applications where very small size and low cost are required. Typical applications are dual band systems where switching between small signal components are required 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, Blue Tooth, and other Rx chain applications. The SW-485 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability. 1 RF1 GND RF2 PIN 1 C=39pF C=39pF Pin Configuration Pin No. 1 Function RF1 GND RF2 V2 RFC V1 Description RF Port 1 Ground RF Port 2 Control 2 RF Input Control 1 Ordering Information Part Number SW-485 SW-485TR-3000 SW-485SMB 2 3 Package Bulk Packaging 4 5 3000 piece reel 6 Sample Board (Includes 5 Samples) 1.
