Infineon has released a module BGSF110GN26 is a single pole ten throw (SP10T) antenna switch module (ASM) optimized for wireless applications up to 3.8GHz. It is the perfect solution for multi-mode handsets based on quad band GSM, WCDMA and LTE. This device is designed to fully support QUALCOMM platforms and is also suitable for other mobile phone chip sets where high performance SP10T is a must.
Infineon’s new simple leadless package technology optimizes performance and cost. The low pass filter based on Infineon’s in-house integrated passive device (IPD) technology takes integration to the next level. The module comes in a miniature TSNP package and comprises a high power CMOS SP10T switch with integrated GPIO controller and harmonic filters for GSM high- and low-band transmit paths. The on-chip controller integrates CMOS logic and level shifters, driven by control inputs from 1.35 to 3.1V.
In typical applications, no external DC blocking capacitors are required if DC is not applied to any of the RF ports. BGSF110GN26 is suitable for smart phones, tablets and mobile phones. It is also the perfect fit for wireless machine-to-machine modules. The switch module configuration is shown in diagram below.
