Introduction

The SKY13405-490LF is a CMOS, silicon-on-insulator (SOI) single-pole, double-throw (SPDT) switch. The high linearity and low insertion loss of the SKY13405-490LF will meet the most stringent requirements of CDMA Simultaneous Voice and LTE (SVLTE) data applications. The switch is a “reflective short” on the isolated port. The SKY13405-490LF SPDT switch is provided in a compact Quad Flat No-Lead (QFN) 2 x 2 mm package. The SKY13405-490LF is designed for high linearity LTE/CDMA handset and data card switching applications. The device can also be used in a variety of other applications that require high performance RF switching. The high linearity and low insertion loss combined with an advanced proprietary fabrication process enable the switch to be used in CDMA and LTE applications. An internal negative voltage generator and decoder eliminate the need for external DC blocking capacitors on the RF ports. Switching is controlled by one voltage input (CTRL). Depending on the logic voltage level applied to the control pin, the RF1 pin is connected to one of two switched RF outputs (RF2 or RF3) using a low insertion loss path, while the path between the RF1 pin and the other RF output pin is in a high isolation state. An internal decoder is used to provide the correct logic to the switch.
