SKY13569-11
RX Diversity FEM with Gain

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.
