Overview
The SKY13380-350LF is a symmetrical, single-pole, four-throw (SP4T) switch designed by Skyworks Solutions Inc. for broadband, high power switching applications. This device is optimized for high linearity and low insertion loss, making it suitable for a variety of multimode applications such as GSM/WCDMA/EDGE datacards and handsets, as well as mobile high power switching systems. The switch is manufactured using Skyworks' state-of-the-art pHEMT process and features integrated logic that uses only two control lines for switch operation. Despite being marked for end-of-life and not recommended for new designs, it remains a significant component in existing systems due to its robust performance characteristics.
