SKY13491-21 Block Diagram Description The SKY13491-21 is a Single-Pole, Fourteen-Throw (SP14T) Switching is controlled by the MIPI decoder. There is an external antenna switch with an integrated Mobile Industry Processor MIPI select pin that enables how the switch responds to power Interface (MIPI ) controller. Using an advanced switching mode triggers. When this pin is grounded, the switch responds to technology, the SKY13491-21 maintains low insertion and high any of the power mode triggers. When this pin is left open, the isolation, which makes it an ideal choice for UMTS, CDMA2000, switch responds to individual power mode triggers. No external EDGE, GSM, and LTE applications. DC blocking capacitors are required on the RF paths as long as no DC voltage is applied. The design features two dedicated GSM transmit ports and three dedicated ultra low-loss TRX ports. The switch also has an The SKY13491-21 is manufactured in a compact, nd rd excellent triple beat ratio and 2 /3 Order Intermodulation 2.5 x 2.9 x 0.8 mm, 22-pin surface mount Multi-Chip Module Distortion (IMD2/IMD3) performance.
