The SKY13498-21 is a single-pole, ten-throw (SP10T) antenna
switch with an integrated Mobile Industry Processor Interface
(MIPI) controller. Using an advanced switching technology, the
SKY13498-21 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 SKY13498-21 is manufactured in a compact,
2.5 x 2.5 x 0.8 mm, 20-pin surface mount Multi-Chip Module
(MCM) package.
