HMC221A / 221AE v02.0911 GaAs MMIC SOT26 SPDT SWITCH, DC - 3 GHz Typical Applications Features the hMc221A(e) is ideal for: RohS-compliant Product t • ISM Applications Low insertion Loss: 0.4 dB M • PCMCIA Wireless Cards Ultra Small Package: SOt26 S • Cellular Applications input iP3: +45 dBm - t Positive control: 0/+3V @ 3 µA D included in the hMc-DK005 Designer’s Kits P S Functional Diagram General Description - S the hMc221A(e) is a low-cost SPDt switch in e a 6-lead SOt26 plastic package for use in gen- h eral switching applications which require very low c insertion loss and very small size. this device t can control signals from Dc to 3 Ghz and is i w especially suited for 900 Mhz, 1.8 - 2.2 Ghz, and 2.4 Ghz iSM applications with less than 1 dB loss. S the design provides exceptional insertion loss perfor- mance, ideal for filter and receiver switching. RF1 and RF2 are reflective shorts when “Off”. the two control voltages require a minimal amount of Dc current and offer compatibility with most cMOS & ttL logic fami- lies.
