Automotive 0.4 to 2.7 GHz SP8T MIPI Diversity Switch

The SKYA21054 is a single-pole, eight-throw (SP8T) antenna switch with an integrated Mobile Industry Processor Interface (MIPI) controller. Using an advanced switching technology, the SKYA21054 maintains low insertion loss and high isolation, which makes it an ideal choice for UMTS, CDMA2000, EDGE, GSM, and LTE applications.

The design features eight linear TRX ports. The switch has an excellent triple beat ratio and second/third order intermodulation distortion (IMD2/IMD3) performance.

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 SKYA21054 is manufactured in a compact, 2.5 x 2.5 x 0.75 mm, 20-pin surface-mount Quad Flat No- Lead (QFN) package.
