0.1 to 6.0 GHz SPDT Switch (AEC-Q100 Grade 2 Qualified)

The SKYA21003 is a CMOS, silicon-on-insulator (SOI) single-pole, double-throw (SPDT) switch. The high linearity and low insertion loss of the SKYA21003 make it an ideal choice for WCDMA data card applications.

The switch is a “reflective short” on the isolated port. The SKYA21003 SPDT switch is provided in a compact Quad Flat No-Lead (QFN) 2 x 2 mm package.
