Description
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.
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 provided in
