The SKY13568-11 is an RX front-end module (FEM) combining
two SP4T switches (input and output switch) with three paths that
include B4, B7, and B17 SAW filters in series with high gain LNAs.
The four separate paths are GPIO selectable with two control
lines.
Using advanced switching technology, the SKY13568-11
maintains low insertion loss in the thru path and high isolation
between paths when RX filtering and gain stages are selected.
Integrated LNAs provide cable loss compensation to overcome
path loss from the antenna to the transceiver.
The SKY13568-11 is packaged in a small, 4 x 3 x 0.8 mm,
17-lead surface-mount package. No external DC blocking
capacitors are required on the RF paths as long as no DC voltage
is applied. The switch can operate over the temperature range of
–35 °C to +90 °C.
