Description The SKY13550-667LF is a dual single-pole, four-throw (2x SP4T) Mobile Industry Processor Interface (MIPI) controlled antenna switch designed specifically for receive diversity in carrier aggregation applications. The 2x SP4T switch is optimized for broadband performance. Using advanced switching technologies, the SKY13550-667LF maintains low insertion loss and high isolation for all switching paths. The high linearity performance and low insertion loss achieved by the SKY13550-667LF makes it an ideal choice for carrier aggregation applications. The switch also exhibits excellent second/third order intermodulation distortion (IMD2/IMD3) performance.

SKY13550-667LF Block Diagram Switching is controlled by an integrated MIPI decoder. The two switches can be configured independently. There are separate registers for each SP4T. No external DC blocking capacitors are required on the RF paths as long as no DC voltage is applied to those paths. The SKY13550-667LF is manufactured in a pact, 1.6 x 2.0 x 0.55 mm, 14-pin surface-mount Quad Flat No-Lead (QFN) package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are...
