Description

The SKY18106-455LF is a single-pole, eight-throw (SP8T)

front-end module (FEM) switch designed for multi-mode,

high-power switching applications that demand low harmonics

and low insertion loss. The switch is optimized for both

2G GSM/EDGE and 3G WCDMA applications. No external blocking

capacitors are required on the RF ports.

The SKY18106-455LF consists of an SP8T switch, GSM transmit

signal harmonic filters, and a serial peripheral interface (SPI)

controller. The low current consumption of the device makes it

very suitable for battery-operated applications.

The switch is provided in a compact 3.0 x 3.8 mm Quad Flat No-

Lead (QFN) package. A functional block diagram is shown in

Figure 1. The pin configuration and package are shown in

Figure 2. Signal pin assignments and functional pin descriptions

are provided in Table 1.
