4 Watt SP3T GaAs Switch, 500 - 2000 MHz SW-449 SW-449 Preliminary Specifications 4 Watt SP3T GaAs Switch 500 - 2000 MHz Features • • • • • MSOP-10 P1dB Greater than 36 dBm Low Insertion Loss: < 1.1 dB @ 2 GHz Positive or Negative 3 to 5 V Control Low Power Consumption: < 200 µA Low Cost Plastic MSOP-10 Package C=100pF C=100pF RFC Gnd Gnd V3 RF3 Pin 10 Description M/A-COM’s SW-449 is a GaAs MMIC SP3T switch in a low cost MSOP-10 surface mount plastic package. The SW-449 is ideally suited for applications where very low current consumption (<200µA), low intermodulation products, moderate power handling and low cost are required. Typical applications include switching for mobile handsets, radio cellular equipment, wireless LANs and other RF control circuits. Pin 1 RF1 V1 Gnd V2 C=100pF C=100pF Ordering Information Part Number The SW-449 is fabricated using a 0.5 micron gate length GaAs pHEMT process. The process features full passivation for increased performance and reliability.
