0.4 to 2.7 GHz SP6T LTE Transmit/Receive Switch with MIPI RFFE Interface

The SKY13526-485LF is a Single-Pole, Six-Throw (SP6T) antenna switch with a Mobile Industry Processor Interface (MIPI).

Using advanced switching technologies, the SKY13526-485LF 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 SKY13526-485LF makes it an ideal choice for UMTS, CDMA2000, EDGE, and LTE applications.

Depending on the logic applied to the decoder, the antenna pin is connected to one of six 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. Switching is controlled by the MIPI decoder. There is an external MIPI select pin that enables how the switch responds to power mode triggers. When this pin is grounded, the switch responds to any of the power mode triggers. When this pin is left open, the switch responds to individual power mode triggers. No external DC blocking capacitors are required on the RF paths as long as no DC voltage is applied.

The SKY13526-485LF is manufactured in a compact, 2 x 2 mm, 14-pin surface mount Quad Flat No-Lead (QFN) package.
