SP8T Antenna FEM Switch: SKY18106-455LF

This SP8T (single-pole, eight throw) FEM (front-end-module) operates in the 0.4-2.2 GHz frequency range and is ideal for 2G GSM/EDGE, 3G WCDMA, and other applications that require low harmonics and low insertion loss.

A SP8T switch, GSM transmit signal harmonic filters, and a Serial Peripheral Interface (SPI) controller make up the SKY18106-455LF. The switch itself comes in a compact 3.0 x 3.8 mm Quad Flat No-Lead (QFN) package, and is manufactured via a state-of-the-art pHEMT process. This switch’s low current power consumption makes it ideal for battery-powered applications.
