SKY13448-001

0.1 – 3.0 GHz SPDT High Power Switch (Single Bit Control) in a WLCSP Package

The SKY13448-001 is a Single-Pole, Double-Throw (SPDT) LTE/WCDMA/GSM transmit switch. Switching is controlled by an integrated GPIO interface with a single control pin. Depending on the logic voltage level applied to the control pin, the antenna port is connected to one of the switched RF outputs (RF1 or RF2) through a low insertion loss path, while the path between the antenna port and the other RF port is in a high isolation state.

No external DC blocking capacitors are required as long as no DC voltage is applied on any RF path.

The SKY13448-001 is provided in a compact 8-bump, 1.1 x 1.1 x 0.36 mm Wafer Level Chip Scale Package (WLCSP) that meets requirements for board-level assembly. Bump diameters are 200 microns with a minimum bump pitch of 400 microns.

Please note: SKY13448-001 is being discontinued and is not recommended for new designs. Recommended replacement part is SKY13489-001.
