The SKY13560-485LF is a single-pole, four-throw (SP4T) antenna
switch with a Mobile Industry Processor Interface (MIPI).
Using advanced switching technologies, the SKY13560-485LF
maintains low insertion loss and high isolation for both transmit
and receive switching paths. The high linearity performance and
low insertion loss achieved by the SKY13560-485LF makes it an
ideal choice for UMTS, CDMA2000, EDGE, and LTE applications.
Depending on the logic applied to the decoder, the antenna pin is
connected to one of four switched RF ports using a low insertion
loss path, while the paths between the antenna pin and the other
RF pins are in a high isolation state. 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 SKY13560-485LF is manufactured in a compact,
2 x 2 mm, 14-pin surface-mount Quad Flat No-Lead (QFN)
