Please note: SKY13569-11 is being discontinued and is not recommended for new designs.
The SKY13569-11 is an RX front-end module (FEM) combining
two SP4T switches (input and output switch) with four paths
(Bypass, B28, B3, and B7).The detail is shown in Figure 1. Each
path is GPIO selectable with two control lines.
Using advanced switching technology, the SKY13569-11
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 SKY13569-11 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.
