Description
The SKY13550-667LF is a dual single-pole, four-throw (2xSP4T)
Mobile Industry Processor Interface (MIPI) controlled antenna
switch designed specifically for receive diversity in carrier
aggregation applications.
The 2xSP4T 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.

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 compact,
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 provided in
Table 1.
