SKY13491-31 Block Diagram Description The SKY13491-31 is a single-pole, fourteen-throw (SP14T) antenna switch with an integrated Mobile Industry Processor Interface (MIPI®) controller. Using an advanced switching technology, the SKY13491-31 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 SKY13491-31 is manufactured in a compact, 2.5 x 2.9 x 0.8 mm, 22-pin surface mount Multi-Chip Module (MCM) 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.
