SKY13489-001

0.7 to 2.7 GHz SPDT High Power Switch (Single Bit Control) in a WLCSP Package

The SKY13489-001 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 SKY13489-001 is provided in a compact 6-bump, 1.135 x 0.735 x 0.400 mm Wafer Level Chip Scale Package (WLCSP) that meets requirements for board-level assembly. Bump diameters are 217 microns with a minimum bump pitch of 400 microns.
