Introduction

This SP4T RF switch is a perfect solution for multimode handsets based on LTE and WCDMA. It has excellent RF performance. The ultra-low insertion loss helps customers to achieve high system sensitivity, the coverage of LTE Tx power and 6GHz enables very broad application. It features DC-free RF ports, external DC blocking capacitors at the RF ports are only required if DC voltage is applied externally. Its on chip MIPI RFFE 2.0 controller is fully compatible with industry standard, with external USID_SEL pin it can support two devices per MIPI RFFE bus.
