0.1-3.0 GHz GaAs SPDT Switch

Please note: SKY13321-360LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY13330-397LF

The SKY13321-360LF is a pHEMT GaAs FET I/C switch. The switch may be used in transmit/receive applications by connecting the RF common port (RFC, pin 7) to either the J1 or J2 port (pin 1 or 4, respectively) using a low loss path (i.e., a positive voltage applied to either V1 or V2 pins).

The switch is manufactured in a compact, 2 x 2 mm, 8-pin exposed pad plastic Quad Flat No-Lead (QFN) package.
