Description

The SKY3 3100-360LF isa bulkacousticwave (BAW) band pass filterina QFN 8L 2 x 2 mm package.Thisfilterhas verylow in-bandinsertionloss,excellentnear-band rejectionand verylow inputand output returnloss. Thisfilterisintended foruse inthe2.4GHz WLAN and ISM bands. The filtercan operateoverthe tempe rature range of -40 to+85 °C. The SKY3 3100-360LF isavailableina lead (Pb)-free, RoHS-compliantpackage. Skyworks offerslead (Pb)-free,RoHS (Restriction of Haz ardous Substances)-compliantpackaging. NEW Parameter Condition Frequency Min. Typ. Max.

CAUTION: Although thisdevice isdesigned to be as robust as possible,ESD (Electrostatic Discharge) can damage thisdevice.This device must be protected at alltimes from ESD. Staticcharges may easilyproduce poten - tials of severalkilovolts on the human body or equipment, which can discharge without detection. Industry-standardESD precautions mus t be employe d at alltimes.

The constructionofBAW resonatorsissimilartothatofparallel platecapacitors.Thisgeometry allowsforveryrobustfilterstobe constructed,withtoleranceofhigherDC voltagesand staticdis - chargesthan thosetoleratedby typicalSAW filters.BAW filter losses and temperaturecoefficientsoffrequency can also be lowerthan thoseoftypicalSAW filtersso thatmor e aggressive near band rejectionrequirementscan be addressed.
