Product Attributes

Introduction

The SGM11124E is a single-pole four-throw antenna switch supporting a frequency range of 0.1GHz to 3GHz. The device features low insertion loss and high isolation, making it suitable for high-linearity reception and 2G/3G/4G transceiver applications, with high-linearity performance advantages. The device is immune to cellular interference, making it ideal for multi-mode multi-band LTE handsets. The device integrates an SP4T RF switch and GPIO controller on an SOI die. The GPIO controller provides internal drivers and decoders for switch control signals, enabling more flexible RF path band and routing selection. As long as no external DC voltage is applied, no external DC blocking capacitors are required on the RF path, saving PCB area and cost. The device is available in a Green ULGA-1.1×1.1-9L package.
