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.

Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.

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
