0.7 to 2.7 GHz SP12T MIPI® Antenna Switch Module

The SKYA21052 is a single-pole, twelve-throw (SP12T) antenna switch with an integrated Mobile Industry Processor Interface (MIPI) controller. Using an advanced switching technology, the SKYA21052 maintains low insertion and high isolation, which makes it an ideal choice for UMTS, CDMA2000, EDGE, GSM, and LTE applications.

The design features two dedicated GSM transmit ports and three dedicated ultra low-loss TRX ports. The switch also 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 SKYA21052 is manufactured in a compact, 2.5 x 2.5 x 0.8 mm, 20-pin surface-mount Multi-Chip Module (MCM) package.
