0.6-2.7 GHz DP12T (SP7T/SP5T) Receive Diversity Switch with MIPI RFFE Interface for Carrier Aggregation

The SKY13484 is a Single Pole, Five Throw (SP5T) and Single-Pole, Seven Throw (SP7T) Mobile Industry Processor Interface (MIPI) controlled antenna switch designed specifically for receive diversity in carrier aggregation applications.

The SP5T switch is optimized for the low band and the SP7T switch is optimized for the high band. Using advanced switching technologies, the SKY13484 maintains low insertion loss and high isolation for all switching paths. The high linearity performance and low insertion loss achieved by the SKY13484 makes it an ideal choice for carrier aggregation applications. The switch also exhibits excellent 2nd/3rd 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 low and high bands. No external DC blocking capacitors are required on the RF paths as long as no DC voltage is applied to those paths.

The SKY13484 is manufactured in a compact, 2.5 x 2.9 x 0.8 mm, 22-pin surface mount Multi-Chip Module (MCM) package.
