0.4 – 2.2 GHz SP8T Antenna Switch With GSM Transmit Filters

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 manufactured using a state of the art pHEMT process, and is provided in a compact 3.0 x 3.8 mm Quad Flat No-Lead (QFN) package.

Features
