per JEDEC J-STD-020
Description
The SKY13296-340LF is a pHEMT GaAs FET IC high isolation,
absorptive single-pole four-throw switch packaged in a lead
(Pb)-free, 4 x 4 mm, 20-lead exposed-pad plastic package for
low-cost commercial applications. The use of external DC
blocking capacitors on the RF ports and in series with the
internal RF terminations enables the user to extend the range
of good return loss to arbitrarily low frequency. This switch
is an ideal building block for filter bank switching.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
