SKY18106-455LF Block Diagram Battery supply voltage: 2.65 to 6.00 V SPI logic (VHIGH = 1.8 V) Description Small QFN (26-pin, 3.0 x 3.8 mm) package The SKY18106-455LF is a single-pole, eight-throw (SP8T) (MSL1, 260 C per JEDEC J-STD-020) front-end module (FEM) switch designed for multimode, high-power switching applications that demand low harmonics and low insertion loss. The switch is optimized for both TM Skyworks Green products are compliant with 2G GSM/EDGE and 3G WCDMA applications. No external blocking all applicable legislation and are halogen-free. capacitors are required on the RF ports. For additional information, refer to Skyworks The SKY18106-455LF consists of an SP8T switch, GSM transmit TM Denition of Green , document number signal harmonic filters, and a serial peripheral interface (SPI) SQ040074. 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.
