SKY13638-700LF

0.4 to 3.8 GHz SP10T LTE Transmit/Receive Switch with MIPI RFFE Interface

The SKY13638-700LF is a single-pole, ten-throw (SP10T) antenna switch with a Mobile Industry Processor Interface (MIPI), Version 2.0.

Using advanced switching technologies, the SKY13638-700LF maintains low insertion loss and high isolation for both transmit and receive switching paths. The high-linearity performance and low insertion loss achieved by the SKY13638-700LF make it an ideal choice for UMTS, CDMA2000, and LTE applications.

The switch also exhibits an excellent triple beat ratio and second/third order intermodulation distortion (IMD) performance. Switching is controlled by an integrated MIPI interface. Depending on the logic applied to the decoder, the antenna pin is connected to 1 of 10 switched RF ports using a low insertion loss path, while the paths between the antenna pin and the other RF pins are in a high-isolation state. No external DC blocking capacitors are required on the RF paths.

Any two arms can be switched on at the same time with multi-closed function for CA applications.

The SKY13638-700LF is manufactured in a compact, 2.4 x 2.4 x 0.50 mm, 20-pin surface-mount Quad Flat No-Lead (QFN) package.
