SKY13551-668LF

0.4 to 3.8 GHz DP10T (SP5T/SP5T) Main/Receive Diversity Switch with MIPI RFFE Interface for Carrier Aggregation

The SKY13551-668LF is a dual single-pole, five-throw (2xSP5T) Mobile Industry Processor Interface (MIPI) controlled antenna switch designed specifically for receive diversity in carrier aggregation applications.

The 2xSP5T switch is optimized for broadband performance. Using advanced switching technologies, the SKY13551-668LF maintains low insertion loss and high isolation for all switching paths. The high-linearity performance and low insertion loss achieved by the SKY13551-668LF makes it an ideal choice for carrier aggregation applications in both main and diversity antenna switching. The switch also exhibits excellent second/third order intermodulation distortion (IMD2/IMD3) performance.

Switching is controlled by an integrated MIPI decoder. The two switches can be configured independently. There are separate registers for each SP5T switch. No external DC blocking capacitors are required on the RF paths as long as no DC voltage is applied to those paths.

The SKY13551-668LF is manufactured in a compact, 1.6 x 2.4 x 0.55 mm, 16-pin surface-mount Quad Flat No-Lead (QFN) package.
