SKY18106-455LF Block Diagram Description The SKY18106-455LF is a single-pole, eight-throw (SP8T) FrontEnd 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 NoLead (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.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY18106-455LF are provided in Table 2. Electrical specifications are provided in Table 3. Table 4 provides the format of the 30-bit SPI_DATA signal. Table 5 describes the values assigned to the contents of the SPI_DATA signal. controlled as described in Table 6. The switch may also be used in one of three modes: active, standby, and isolation. These modes are controlled by bits [15:11] of the SPI data word. NOTE: The SPI_VDD signal (pin 25) must be pushed high for 2 ms before the first SPI command is sent to program the switch within the operating temperature range (TOP). The SKY18106-455LF can operate in one of 16 states as listed in Table 6.
