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.
