Description
The SKY12406-360LF is a pHEMT GaAs FET IC single bit attenu-
ator packaged in an 2 x 2 mm 8-lead exposed pad plastic package
for low-cost commercial applications. This attenuator has an LSB
of 12 dB. The SKY12406-360LF is particularly suited where high
attenuation accuracy, low insertion loss, and low intermodulation
products are required. Typical applications include cellular radio,
wireless data, and wireless local loop gain level control circuits.
NEW Skyworks Green™ products are RoHS (Restriction
of Hazardous Substances)-compliant, conform to
the EIA/EICTA/JEITA Joint Industry Guide (JIG)
Level A guidelines, are halogen free according to
IEC-61249-2-21, and contain <1,000 ppm antimony
trioxide in polymeric materials.
